v0.3-beta (Experimental)

Changes in this release:

• CSV formatting of log messages has been added to match master branch.
• Preliminary IDM parsing is implemented. Logging formats may change since IDM messages are much larger than SCM messages.
• The preamble search routine has been optimized.

Future:

• The only real bottleneck left is magnitude calculation, I've written and tested the alpha max plus beta min algorithm which is quite a lot faster. This will likely be added as an option through a cli flag since it's an approximation and I'm not sure what affect it will have on reception just yet.
