Feature-Request: configurable letter-spacing

[futureweb]

Hey Drew,

while experimenting with different Fonts I noticed that it would be very handy to be able to configure letter-spacing for the Captcha - as some Fonts tend to be very tight together (unreadable) and others tend to be too wide ...
Maybe it would make sense to add this as an Option? ;-)

thx
Andreas Schnederle-Wagner

btw) my current config/font (at Site bottom) - guess that should be bot-proof again ;-): https://www.futureweb.at/

Good idea
