refactor(indent)!: Rework indent, aligned indent

indents now use @indent.X style captures, and indent.PROP for properties to set on those captures, as documented in the help.

Captures are:

indent.auto
indent.begin
indent.end
indent.dedent
indent.branch
indent.ignore
indent.align
indent.zero

Properties are:

indent.immediate
indent.start_at_same_line
indent.open_delimiter
indent.close_delimiter
indent.increment
indent.avoid_last_matching_next

Multiple opening delims on one line and multiple closing on a line are collapsed so as not to over indent,

The final line of @indent.align blocks which must in some cases be treated specially to avoid clashing with the next line is treated the same regardless of whether the @indent.align capture actually uses aligned indentation or just normal indentation. The indent.avoid_last_matching_next property controls this.

Adjust python to use these.

List, set, dict and tuple all use @indent.align which permits both hanging and aligned styles.

Finally, try: on it’s own will indent when typing live but make no guaranteeds about whole-file formatting.
