[New-bugs-announce] [issue41622] Add support for emoji-data.txt and emoji-variation-sequences.txt to unicodedata

[jack1142]

New submission from jack1142 <kuba.kuczys at gmail.com>:

`emoji-data.txt` and `emoji-variation-sequences.txt` files were formally pulled into the UCD as of Version 13.0 [1] so I think that unicodedata as a package providing access to UCD could support those as well.
In particular:
- `emoji-data.txt` lists character properties for emoji characters [2] 
- `emoji-variation-sequences.txt` lists valid text and emoji presentation sequences [3]

Data from `emoji-variation-sequences.txt` can be used to ensure consistent rendering of emoji characters across devices [4] (`StandardizedVariants.txt` has a similar purpose for non-emoji characters).
I'm not entirely sure of the use cases for `emoji-data.txt`, but because it's also newly added in UCD 13.0.0, I figured I at least shouldn't omit it when making this issue.
