Acronym spacing

[microraptor]

Here is one last minor improvement suggestions from me. I noticed that the pacing of acronyms sounds weird in the generated files. Trying it out at the online demo Generator, I personally think the acronym pacing sound much better, if we don't use spaces between letters. So OSD, VTX, etc. instead of "O S D", "V T X". This seems especially important for longer phrases ("VTX 400 milliwatts"). However, this is very subjective. My apologies for not testing this before audio files were generated, because quite a few of them were in my actually in my PR.

If you decide to merge this, these are the audio files, which would be affected by the change:

Hm... strange... I did random sample of

V T X on
VTX on

V T X 600 milliwatts
VTX 600 milliwatts

dynamic T X power
dynamic TX power

F P V angle mix active
FPV angle mix active

O S D on
OSD on

D B
DB

R P M
RPM

and didn't notice any difference... but this was with Irish Emily... was there a particular speaker that was more prone to space it out?

Scratch that... Libby seems to like saying it consistently, but UK and US space it out. 🤦
