arp242/uni v2.7.0 on GitHub

Improve -format flag:
- Add %name as an alias for %(name l:auto); this is a lot less typing and requires less shell quoting, and >90% of the time this is what you want.
- Automatically prepend character, codepoint, and name if the format flag starts with +; for example:
```
% uni identify -f +'%unicode %plane' a
             Name                 Unicode Plane
'a'  U+0061  LATIN SMALL LETTER A 1.1     Basic Multilingual Plane
```
This should make quickly printing some property a lot quicker.
Align and colourize JSON output.
Update CLDR information, adding significantly more aliases for emojis.
Add cells column, which returns how many cells a codepoint will display at (0, 1, or 2).

Add aliases column, which lists the alias names. Also add this to the default output:

% uni s factorial
     CPoint  Dec    UTF8        HTML       Name  Aliases
'!'  U+0021  33     21          &excl;     EXCLAMATION MARK [factorial, bang]

Add refs columns, which references other related/similar codepoints:

% uni p -q U+46 -f '%(name): %(refs)'
LATIN CAPITAL LETTER F: U+2109, U+2131, U+2132

% uni p -q U+46 -f '%(refs)' | uni p
     CPoint  Dec    UTF8        HTML       Name  Aliases
'℉'  U+2109  8457   e2 84 89    &#x2109;   DEGREE FAHRENHEIT
'ℱ'  U+2131  8497   e2 84 b1    &Fscr;     SCRIPT CAPITAL F [Fourier transform]
'Ⅎ'  U+2132  8498   e2 84 b2    &#x2132;   TURNED CAPITAL F [Claudian digamma inversum]

Allow arguments to printto start or end with a comma or slash. This comes up when copy/pasting some list of codepoints from another source; there's no real reason to error out on this.
Allow listing unicode versions with uni list unicode and planes with uni list planes.
uni list without arguments errors, instead of listing all.
Add h format flag to not print the header for this column.
