2823bebd23 refactor(library/init/lean/parser/parsec): message.pos: replace with iterator 
This allows efficient recovery from a parse error as well as implementing
`has_to_string` for `message`

898e14cdf5 fix(library/init/lean/parser/parsec): orelse: do not backtrack on success 
This change makes backtracking behavior more predictable and
matches Parsec and Megaparsec's behavior. While the original Parsec paper
motivates the old behavior by arguing it implements the "longest match" rule,
this is obviously only true in a very limited sense.

389e9b7b49 feat(library/init/lean/parser/parsec): use [inhabited μ] instead of unit for custom message type of basic parsers 
In hindsight, this seems to simplify usage without compromising static typing much

9db0724bf1 refactor(library/init/lean/parser/parsec): monad_parsec: move from monad_lift/monad_map to direct primitives 
This breaks the code for variable-length tokens that depended on lifting
`parsec` into `read_m`. Either `read_m` could be parameterized by its state,
or we just hard-code all variable-length tokens.
