parse: Add remove_whitespace pass

make: Remove hypothesis statistics and seed ...

We don't really need these.

make: Remove _build/NewLang when building ...

I'm fairly sure Python alrady does this. Better safe than sorry.

parse: Move to oldparse ...

This is in preparation of writing a new parser.
Once the new parser is ready then this code can be junked.

testss: tokenize: Add documentation on the expected behaviours

tests: tokenize: Give garbled tokens to the classifier ...

This helps prove that the classifier only classifies full tokens, not
substrings.

tokenize: Add shebang types

tokenize: Classify language keywords

tokenize: Add booleans

tokenize: Add is_newline and is_whitespace functions

test: tokenize: Move draw_tokens_list to draw_tokens_to_split ...

While we're at it include the source flattening code.

tests: tokenize: Add a draw_token_classified strategy

tests: tokenize: Use random tokens again for locations ...

By using random tokens and passing that set to the test we now have both
random values, random locations and random types to help prove that the
location pass only uses types and length for locating.

tests: tokenize: Test location using types only

tokenize: Move classify_tokens to before locate_tokens

tokenize: Use type for locating newlines ...

This allows us to test locating with a broader variety of inputs, not
just what we pass to split_tokens.

tokenize: Add NEWLINE token type ...

This isn't used yet but is intended to make location handling easier.

tests: tokenize: Add more accurate comments

tests: tokenize: Have draw_token_* use draw_token_random

tests: tokenize: Put generic draws at top of file

tokenize: Add tokenize wrapper function

tests: tokenize: Add comments

tests: tokenize: Run classification with random input

tokenize: Add classify_tokens to set token types

tests: tokenize: Rename draw_token to draw_token_random

tokenize: Add WHITESPACE TokenType ...

This will be used later.

tests: Use random token types for tokens

tokenize: Add type value for token type

src: tokenize: Rename symbol to token

tests: Generate random locations for symbols ...

This requires adding a new higher-order strategy to set the location of
a symbol.
