feat: support \mathscr command

Fix: #190.

Obviously there has been a solution to mathscr a long time ago, but I don't know why mitex has not supported it. It may be a font problem or your team has corresponding considerations. Because I have personal needs, I made a PR. If it is different from your expectations, you can abandon this change. I think it should at least be usable first and then consider optimization.

Update the logic to handle multiple characters rather than a single one.

#mitex(`\mathscr{ABCDEFGHIJKLM}`)
#mitex(`\mathscr{NOPQRSTUVWXYZ}`)
#mitex(`\mathbf{\mathscr{ABC}}`)

The \mathscr command is typically provided by the mathrsfs package, while the RSFS (Ralph Smith's Formal Script) font files used by this package only provide a single font weight (the standard weight). Therefore, it does not render in bold in LaTeX.

feat: support some missing eqq commands

Partial fix: #173.

Some unicode of symbols cannot be found, but I found that some LaTeX commands are actually obtained by length: 1em, angle: 20deg, this visual effect is consistent with LaTeX.

#let syms = (
  "nsubseteqq": math.cancel(angle: 20deg, length: 1em, "\u{2AC5}"),
  "nsupseteqq": math.cancel(angle: 20deg, length: 1em, "\u{2AC6}"),
  "gtrapprox": math.gt.approx,
  "ngeqq": math.cancel(angle: 20deg, "\u{2267}"),
  "nleqq": math.cancel(angle: 20deg, "\u{2266}"),
  "nleqslant": math.cancel(angle: 20deg, length: 1em, math.lt.eq.slant),
)

#table(
  columns: 2,
  align: (center, center),
  stroke: none,
  [*LaTeX Command*], [*Rendered Result*],
  ..syms.pairs().map(((k, v)) => (raw("\\" + k), $#v$)).flatten()
)

Tests

#table(
  columns: 4,
  stroke: none,
  align: (center, center, center, center),
  inset: 8pt,

  [\\nsubseteqq], mitex(`\nsubseteqq`), [\\nsupseteqq], mitex(`\nsupseteqq`),
  [\\gtrapprox], mitex(`\gtrapprox`), [\\ngeqq], mitex(`\ngeqq`),
  [\\nleqq], mitex(`\nleqq`), [\\nleqslant], mitex(`\nleqslant`),
)

Thanks! I think there are only some simple CI issues here.
