David Sutton ee6046cab0 alsa.go: Add chunkingRead function to abstract reading from the alsa buffer (#440) 
The chunkingRead function allows the record period to not impact on the recording buffer size of the audio. This should allow for less issues related to alsa buffer reading.

David Sutton c8f846f87d alsa: Fix sample rate negotiation (#441) 
This change fixes the sample rate negotiation functionality, by making a comparison against the value of the slice and not the index.

cmd/audio-netsender,device/alsa,revid: swap out ring buffer for pool buffer 
Names of config fields have been left unchanged since they appear to be lexically
coupled to behaviour and so require greater care.

To check that the IsRunning method is working, some tests are needed. These tests shall be skipped when an AVdevice is not connected, such as when testing within Circle-CI.

Trek H cd63d0d95a alsa: unexported ringbuffer chunksize 
Chunksize can be calculated without needing an ALSA device instance.

Added a DataSize function to pcm package for calculating size of pcm data given relevant attributes.

Removed ChunkSize from config revid config struct.

Changed NewByteLexer to accept an in rather than a pointer.

Trek H 5e472ba4c9 pcm: refactored to be general not alsa only 
Addition of new structs and helper functions for passing around pcm clips/buffers and their formats so that we don't have to import and rely on yobert/alsa code.

Updated any commands and alsa package to use refactored code.
