This PR introduces the modules `Std.Data.DTreeMap.Raw`,
`Std.Data.TreeMap.Raw` and `Std.Data.TreeSet.Raw` and imports them into
`Std.Data`. All modules related to the raw tree maps are imported into
these new modules so that they are now a transitive dependency of `Std`.
This PR provides tests for those tree map functions that are not
verified yet.

the head of `keys`, `keys` and `toList` are ordered and `getKey*
t.minKey?` equals the minimum.

the hash map in #7289.

This PR renames the member `insert_emptyc_eq` of the `LawfulSingleton`
typeclass to `insert_empty_eq` to conform to the recommended spelling of
`∅` as `empty`.
See also #7447.

interactions with other functions for which lemmas already exist.

This PR provides lemmas about the tree map function `insertMany` and its
interaction with other functions for which lemmas already exist. Most
lemmas about `ofList`, which is related to `insertMany`, are not
included.

This PR provides lemmas about the tree map functions `foldlM`, `foldl`,
`foldrM` and `foldr` and their interactions with other functions for
which lemmas already exist. Additionally, it generalizes the
`fold*`/`keys` lemmas to arbitrary tree maps, which were previously
stated only for the `DTreeMap α Unit` case.
A later PR will make the hash map functions `fold` and `revFold`
internal and also update their signature to conform to the tree map and
list API. This is out of scope for this PR.

This PR changes the order of arguments of the folding function expected
by the tree map's `foldr` and `foldrM` functions so that they are
consistent with the API of `List`.

This PR provides lemmas about the tree map functions `keys` and `toList`
and their interactions with other functions for which lemmas already

is fixed.

This PR provides proofs that the raw tree map operations are well-formed
and refactors the file structure of the tree map, introducing new
modules `Std.{DTreeMap,TreeMap,TreeSet}.Raw` and splittting
`AdditionalOperations` into separate files for bundled and raw types.

This PR provides lemmas for the tree map functions `get`, `get!` and
`getD` in relation to the other operations for which lemmas already
exist.
Internally, the `simp_to_model` tactic was provided two new simp lemmas
to eliminate some common complications that require `rw`'ing before
using `simp_to_model`. However, it is still necessary to sometimes
`revert` some hypotheses.

`erase`.

This PR implements the `getKey` functions on the tree map. It also fixes
the naming of the `entryAtIdx` function on the tree set, which should
have been called `atIdx`.

This PR implements the methods `min`, `max`, `minKey`, `maxKey`,
`atIndex`, `getEntryLE`, `getKeyLE` and consorts on the tree map.
In order to implement the proof-based functions such as `min` and
`getEntryLT` in `Queries.lean`, it was necessary to extract `Balanced`
and `Ordered` into new files so that they can be used from
`Queries.lean`.

This PR adds some lemmas about the new tree map. These lemmas are about
the interactions of `empty`, `isEmpty`, `insert`, `contains`. Some

in a later PR.

This PR introduces ordered map data structures, namely `DTreeMap`,
`TreeMap`, `TreeSet` and their `.Raw` variants, into the standard
library. There are still some operations missing that the hash map has.
As of now, the operations are unverified, but the corresponding lemmas
will follow in subsequent PRs. While the tree map has already been
optimized, more micro-optimization will follow as soon as the new code
generator is ready.
