Match Expressions operator alignment

[jacobcassidy]

Currently, there are no coding style rules for match expression operators. I suggest having the double-arrow operators in alignment, with the option of breaking out of alignment when using more than one conditional expression.

For example, this is not aligned:

$asset_dir = match ($asset_type) {
	'style' => 'build/base/css',
	'script' => 'build/base/js',
	'editor_ui_style' => 'build/blocks/css',
	'editor_ui_script' => 'build/blocks/js',
	default   => 'build/base'
};

The desired alignment:

$asset_dir = match ($asset_type) {
	'style'            => 'build/base/css',
	'script'           => 'build/base/js',
	'editor_ui_style'  => 'build/blocks/css',
	'editor_ui_script' => 'build/blocks/js',
	default            => 'build/base'
};

An example of breaking out of alignment with multiple conditional expressions for a match:

$asset_dir = match ($asset_type) {
	'style'            => 'build/base/css',
	'script'           => 'build/base/js',
	'editor_ui_style'  => 'build/blocks/css',
	'editor_ui_script' => 'build/blocks/js',
	'expession_1', 'expression_2', 'expression_3' => 'some value',
	default            => 'build/base'
};
