fix(config): allow disabling FEC by setting fec_percentage=0 (previously this was treated as 20)

[andygrundman]

Description

fec_percentage was mistakenly defined as a value between 1 and 255, preventing it from being disabled with 0. This change defines it as 0-100 as you would expect from the name.
