star spacing

[andreashuber69]

This somewhat duplicates what has been discussed before, but AFAICT has not been succinctly condensed into a feature request before. Most people seem to have a very strong opinion about this, which is probably why eslint can be configured to put the star just about anywhere, with the rules generator-star-spacing and yield-star-spacing. It would be nice to have similar configurability in dprint.

Here's an incomplete list of locations where star spacing would apply:

class A {
    public *before();
    public* after(); // yes, this is legal
    public static *before();
    public static* after(); // yes, this is legal
}

const anonymous = function *() {
    yield 1;
    yield 2;
};

const before = function *before() {
    yield *anonymous();
};

const after = function* after() {
    yield* anonymous();
};

In my experience most are not consistent about star spacing, some insist the star has to go with the function name function *func() (space before) but then happily write yield* func(); (space after), which happens to be the default setting with eslint.

IMO, dprint currently formats inconsistently as well, e.g. yield* and function* but private *whatever().
