Support single-level indentation after opening delimiter (similar to PEP-8)

[flixha]

Thanks a lot for developing mh_style!

What kind of feature is this?

• New feature in MISS_HIT

Your MATLAB/Octave environment

• MATLAB R2021b

MISS_HIT component affected

• Style checker

Describe the solution you'd like
It would be nice if it could support indentation style similar to PEP-8 concerning e.g., function definitions and calls, allowing to:

• either align indented lines with the opening delimiter:

  foo = package.TopClass.long_function_name(var_one, var_two, ...
                                            var_three, var_four)

• or, when the only phrase appearing after the opening delimiter is " ...", to continue at a single-indentation level:

  foo = package.TopClass.long_function_name( ...
      var_one, var_two, var_three, var_four)

Currently accepted style
Currently, mh_style only accepts the following styles, which doesn't help much with limiting the length of lines:

foo = package.TopClass.long_function_name( ...
                                          var_one, var_two, var_three, var_four)
foo = ...
    package.TopClass.long_function_name(var_one, var_two, ...
                                        var_three, var_four)

Sounds like an interesting idea. It's been a while since I touched the indent code so not sure how easy it'll be but I'll see what can be done.
