v1.5.4

Here are the updates in v1.5.4:

1. The README file now has js code for blocks every method, for improved legibility and copy/pasting.

2. There were also several bug fixes:

• note() method's position argument is working as expected
• stutter() was refactored and simplified to retain pitch of the input pattern
• dirsamp() was fixed to address a bug where it would never find a sample if the lookup value was == 1.

3. Oscillator methods no longer have a sampleRate argument, which was probably overkill to include to begin with: cosine(), phasor(), rect(), sine(), circle(), square(), tri()
