v7.0.0: TIM-v3!

[bczsalba]

This release brings completely re-written TIM implementation to the library. It is significantly faster (~2x for markup without macros, >10x for markup with macros) than the previous version, and it's a lot easier to maintain and improve upon.

The previous hyperlink syntax ([!link(https://example.org)]Example site[/!link]) is now deprecated in favour of a new, much simpler one:

[~https://example.org]Example site[/~]

There have also been a couple of changes to SVG exports to make them more accurate and aesthetically pleasing. We also support the inverse style for them as well!

API updates

Type	Change	Alternative	Comment
Removal	get_applied_sequences	A custom tokenization based implementation	This function was no longer used internally, and if someone needed it the new tokenizers are a much more performant and smart way to go about implementing it.
Removal	MarkupLanguage.prettify_markup	highlight_tim	Using regex-based highlighting allows the output markup to be completely identical char-by-char to the source, whereas the previous token based implementation had a tendency to change things around. It's also much less LOC and faster.
Deprecation	Markup hyperlink syntax !link(https://example.org)	The new ~https://example.org syntax	Previously hyperlinks were implemented as macros, but they were very messy under the hood. A first-class syntax for them is vastly superior.
Refactor	The role of StyledText	N/A	Previously, StyledText was meant to be barely detectable when used. It was returned in various places, but wanted to not be a thing you thought about often. Now it's on an opt-in basis, and it no longer tries to pass as a str. It's immutable, and is only meant to be generated by MarkupLanguage.group_styles or StyledText.group_styles. You can also now create them from markup, not just ANSI-coded text.
