WIP Lua Script for Davinci Resolve to convert Subtitles (SRT) tracks to Text+ media comps.

Srt2TextPlus.lua

--[[
	SRT to Text+

	Author Shinda Singh <ss@ss44.ca>

	This is a Davinci Resolve Script or at least an attempt at one
	that reads text from a subtitle track and converts them to text+ comps so that
	effects can be applied (think Mr Best Subtitles)

	Unfortunately this is kind of stalled since it only creates the text+ with text
	but fails to place them in the correct position just couldn't figure out how
	with the limited documentation.

	Shoutouts: https://note.com/hitsugi_yukana/n/n1601e81df8d7
	
	A similar and more working script / plugin can be found:
		https://www.youtube.com/watch?v=DKwNJm4hajo

	But my main beef with this implemtnation is it requires an external app to launch Davinci
	so this was an attempt to find a cleaner solution, which I did not.
