Added the ability to use KmM as abreviatures

[Imeguras]

The commit is anything but special, and i dont know if the owners intended the way it was before as its a really simple "fix"

Basically it enables the use of different decimal units abreviations other than just the lowercase k in this case it allows K, m and M(the m is for million)

If you are wondering why would i make this, i use impact and apparently on the version im using .goto -xk y zk apparently does not work, due to me using baritone directly and impact interchangibly i started to think it was a baritone issue but apparently it isnt any way i might as well add something to it
