bat: Add 'readcapture' option to support analyzing external audio

alsa-project/alsa-utils pull request #166 was opened from tbird20d:

If audio data is captured on another device (ie we are NOT using loopback mode), then allow alsabat to analyze that data, by passing a filename reference on the command line.

Add the '--readcapture' option to the argument parser. When this option is specified, avoid doing a local capture, and instead just read the audio data from the indicated file, and analyze that.
