More customization options to subtitles (colors, fonts, placement)

[krutburken]

Describe the feature you'd like

Since we now (finally!) are able to set the font size and disable the background, I'd also like to request the options to customize the color, font and placement on screen, similar to what's available in Kodi.

Was thinking of having a look at this, ill submit a pull request having a color picker, really i would like some opinions of colors, maybe using the Netflix subtitle colors as suggestions, what do people think? These are what i get: ffffff,000000,c80000,00c800,0000c8,eedc00,d60080,009fda

You can already change (background) color by just changing the line:

Here is an example by changing this line to: span.setSpan(new PaddedLineBackgroundSpan(ContextCompat.getColor(requireContext(), R.color.grey_transparent), SUBTITLE_PADDING, horizontalGravity), 0, span.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
