Add `regolith run [profile] --selcted-filters <pattern>` (we need better name for the flag)

[Nusiq]

The --selected-filters flag would let you provide a pattern used for selecting which filters should be executed from the profile.

Examples:

• 1 - first filter
• ..3 - first 3 filters
• 2..4 - filters 2,3,4
• 2,4,1 - filters 2,4,1 (in that order (?))

Looks like this one adds quite a bit of complexity. This would mostly be used for debugging I presume?

[Nusiq]

Yes. The most important feature is to implement ..n (run first n filters). This enables tracking what happens in regolith internally while it runs the filters. I think coma separated values are also important. SOmeone could have some kind of beautify filter which would format outputed files at the end. In this case someone might want to debug using command with ..<n>,<las_index> to have the code nicely formatted.

Debugging which filter breaks something can be done with either commenting out a portion of used filters or adding a "disabled": true to the filter in a profile. In case someone has some kind of beautify filter or minify filter, they can have a separate profile for development without those filters.

A possible solution could be to have a way to pass some data to when expression maybe like this:

regolith run --data "disableMinify=true,disableBeauitfy=true"

And then you would add a when field to the filter like this

{
  "when": "!disableMinify"
}

I think this feature is not worth the effort.
