Gwilym Inzani 2ab3fa79e1 Notes are 1 indexed, not 0 indexed 
Versions of xmrs below 0.4.1 (unreleased, 0.4.2 is on crates.io but
0.4.1 is in the repo) have a bug where they swap linear and amiga
frequencies. This caused all old versions of agb (which were using
version 0.3) to use the amiga frequency table rather than the linear
one. Technically it sounds slightly wrong but it is kinda hard to tell.

Since agb 0.20.0, we are now using xmrs 0.5, which correctly reports the
frequency type for the XM file. That pointed out an error in the
note_to_speed method for linear frequencies (since those are now being
used). It turns out that the formula for calculating the frequency
expects a 0 based index for the note, but we were passing a 1 based
index for the note. Moving this down a note fixes the issue where things
were being played at the wrong frequency.
