This PR provides tree map lemmas about the interaction of
`containsThenInsert(IfNew)` with `contains` and `insert(IfNew)`.

This PR adds all missing tree map lemmas about the interactions of the
functions `empty`, `isEmpty`, `contains`, `size`, `insert(IfNew)` and
`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 `getThenInsertIfNew?` and `partition` functions
on the tree map.

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
lemmas about the interaction of `contains` with the others will follow
in a later PR.

This PR implements the methods `insertMany`, `ofList`, `ofArray`,
`foldr` and `foldrM` on the tree map.

This PR adds some deprecated function aliases to the tree map in order
to ease the transition from the `RBMap` to the tree map.

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.
