tests: parse: Move text tests to its own file

tests: parse: Move bool tests to its own file

tests: Move parse to its own directory

tests: parse_boolean -> parse_bool

tests: Move draw_token_by_value to syntax

parse: Clear notes as first parse step

parse: Add clear_notes function to handle removing comments

tests: Remove dead code in draw_note_value_token ...

I probably kept this when copy pasting from draw_text_value_token.

syntax: Add peeking to SyntaxStream

parse: Put skip_note in its own class for testing

parse: Wrap parse functionality to allow mock testing

parse: Parse boolean values

parse: Add skip_note for parsing notes

parse: Add ParseError and ParseErrorException for error reporting

syntax: Note that files don't have to use Unix new lines ...

They also don't have to be normalized.

tokenize: Support CR LF new line sequences

tokenize: Add more new line symbols

parse: Ignore whitespace in text, instead join words with spaces ...

This cuts down on complexity as now only the tokenizer deals with
whitespace and makes whitespace no longer a factor in the language.

docs: Bump copyright

.gitignore: Hide all __pycache__ directories

make: Remove pytest and mutmut cache

syntax: Drop NewLang version keyword ...

Bundling NewLang solves the issue of version compatibility.

syntax: Drop support for shebangs ...

Shebangs are useful for writing scripts, but they assume an install of
NewLang separate from the application.

I don't plan to support that, only bundling of NewLang and its scripts.

docs: Clarify that we mean code points, not characters

syntax: Rename SyntaxLocation's column to offset ...

We don't know anything about columns or displaying the code points in
our source file, so be clear it's an offset and not a column.

tests: parse: Add helper insert_random function ...

This is just to help clean up some complicated looking code.

tests: parse: Document draw_token_by_value

syntax: Re-organize file

tests: syntax: Rename draw_token_location to draw_syntax_location

tests: tokenize: Move syntax tests to new file
