initOptions: sub-text-scale not working on iOS

[VoidBGS]

Hello everyone,

I have been using this library for my application for the past two years and when I updated it to the newest version it seems that the initOptions were broken on iOS. Afterwards, they were fixed in this commit #167. Although this fixed many of my problems regarding the player, it did not fix my issue with the sub-text-scale option. I've even tried forcing it in the RCTVLCPlayer.m to no avail. Does anyone else also have trouble with this and is there any other way to resize subtitles?

The same code and with same options does change the font size of the subtitles on Android, with the exception that I must add --subdec-align=0 to the options, otherwise the font size does not change.
