Set the number of LoggerSet Buffers used by fast-logger

A value of Nothing means to use getNumCapabilities. Higher is more performant, but may deliver messages out of order. The defualt is set for TTY usage (so, 1), but is also changed through setLogSettingsFormat is used.

Support for this option depends on your version of fast-logger:
