Environment

Cascadia Code version number: 2102.25
Application (with version) used to display text: Visual Studio 2019 (16.9.4)
OS platform and version: Windows 10 (version 1909)
Screen resolution (i.e. 220dpi): 3440x1440 with DPI=100%

Steps to reproduce

Install CascadiaCode.ttf (variable) for all users. Then, in Visual Studio simply type "===>" like this:

ligature-error

The artifact is only observed for three equal signs. Any other number produces a gap free arrow.

Thanks! It looks like I need to add another exclusion for that specific case. Will do so :)

A large set of bug fixes identified while working on the Italic, but solving
Github reported issues. 

## PR Checklist
- [x] Closes #422 - Bitcoin added
- [x] Closes #427 - FFFD glyph added
- [x] Closes #418 - top bar corrected
- [x] Closes #433 - hinting corrected to ensure alignment
- [x] Closes #435 - adds consistent ligature form for `=>>` `<<=` `=<<` and
  `>>=` (the infinite arrows still work with addition of more equals)
- [x] Closes #443 - ligature now ignores (*) scenario
- [x] Closes #454 - adds ignore to prevent equal_equal ligature from showing up
- [x] Closes #467 - Not specifically sure of the problem here, but suspect that
  it will be fixed with this - update.
- [x] Closes #477 - fixed
- [x] Closes #478 - fixed
- [x] Closes #479 - fixed
- [x] Closes #480 - fixed
- [x] Closes #481 - JetBrains enumerates fonts weird. I've modified the
  internal naming so that it will register Cascadia Code correctly. Also
  aligned postscript naming with Google's recommendation, so will show up as
  "Regular" instead of "Roman". Still works in Word!


Other Cascadia Code fixes:
- General improvement of weight balancing
- Weight of lowercase rounds reduced in the Bold weight in Cascadia Code.
- Weight of Capital stems increased in Extralight weight in Cascadia Code. 
- Tweaked weight of ogonek in ExtraLight.
- Added a localized form for ij and IJ should a user chose to use those
  codepoints and want an accented version.
- Split fraction bar at heavier weights to improve clarity of fractions.
- Adjusted standard box drawing characters to align with GDI metrics, and added
  a complete set of DWrite-specific ones that align with sTypo (using `rclt`).
- Ironed out some tiny inconsistencies in the <$ $> <$> ligatures which I'm
  sure no one will ever notice. 
- Fixed centering of braces and some hyphens.
- Fixed inconsistency between semicolon/colon and period weight in bold. Also
  fixed slight differences in hyphen-like glyphs in bold. You're as surprised
  as I am. 
- Increased weight of underscore in bold.
- Adjusted weighting of Ɫ.
- Changed design of commaaccent, commaaccentmod commaturnedabove and commaabove
  to be more distinguishable (following design of quotes).
- Increased height of βδθλ to align with the ascender height. They were too low
  before. 
- Fixed descents of various greek lowercase glyphs that were inconsistent. 
- Modified ξ weighting. 
- Felt ligated, might edit later.
- Tweaked ªºⁿʷʸᶿᶻ⁰¹²³⁴⁵⁶⁷⁸⁹ in imperceptable ways. 
- Corrected some additional interpolation bugs

I do enjoy giving Dustin presents.
