Dump and load correct volume and pitch values for T6 sound aliases

[Jbleezy]

I became a scholar of music theory to figure out what these values were representing.

BO1 and BO3 sound aliases have volume values ranging from 0 to 100, and pitch values ranging from -2400 to 1200.

The amp ratio value is due to 100 decibels being equal to 100,000 amplitude, but the value is stored in 16 bits.

Thanks for the PR :) Your guess about the input formats was very correct.
I reversed a bit of the T5 modding tools to find out the exact formulas used though, so i adjusted them a bit.
And made the code a bit better to read.
Thanks a lot :D

Oh also: I will follow up with another Pull Request to refactor a good bit of the loading and dumping code.
Your changes are already backwards incompatible so i thought i could just as well add a couple more to not break existing csvs more than once.
It should fix a good amount of weird quirks, small mistakes and missing data, so afterwards it might be worth checking whether the odd sound issues are fixed.
