chore: restore files that generated the type-parser

[jpivarski]

This is how src/awkward/types/_awkward_datashape_parser.py was made.

These files were taken from 4ba1dbb (#1514), the last commit before they disappeared in the v1 → v2 transition. I think this was their final state—I think they weren't developed any further. (Am I missing anything, @reikdas?)

These should remain in the dev directory in case we ever need to make changes to the grammar or update the generated file to a new Lark version or a new Python version.

For reference, the auto-generated file was made according to the procedure documented in

• https://lark-parser.readthedocs.io/en/latest/examples/standalone/json_parser_main.html
• https://lark-parser.readthedocs.io/en/latest/tools.html
• http://blog.erezsh.com/create-a-stand-alone-lalr1-parser-in-python/

Since this PR only touches files in the dev directory, I'm going to merge it without review.

Huh, this was around at some point. Didn't realise we lost them! Good catch.

@ianna was right (in a now-deleted comment). These were saved, but they were in the studies/ directory, rather than dev/. The files I included here are from an intermediate state between studies/type-parser and studies/type-parser-2, so I put these files into studies/type-parser-1.5.

These diffs are not too big:

diff dev/typeparser/parser.py studies/type-parser/parser.py
diff dev/typeparser/type-grammar.lark studies/type-parser/grammar.lark

I can confirm that studies/type-parser-2 (added in #1514) is the most recent; it added our current src/awkward/types/_awkward_datashape_parser.py and there have been no substantial changes to it since then.

One test is failing because of #2920. I'll get to that later.

[jpivarski]

The other tests aren't running because this PR only puts data into the studies/ directory, so it's sufficiently tested to merge.
