Chris Robinson d9bf4f7620 Allow increasing the maximum source limit
If the requested number of mono and stereo sources exceeds 256, the source
limit will be expanded. Any config file setting overrides this. If the device
is reset to have fewer sources than are currently allocated, excess sources
will remain and be usable as normal, but no more can be generated until enough
are delated to go back below the limit.
