1.) Changed logic of `set_affinity` to now use physical cores rather than
knowing the bitmask. Rather than having to know a bitmask, users can
provide a numerical instance of one or more CPU cores
(numbered 0-63).
This is done via function `cpus_to_bitmask`.
Functions Added:
a.) bitmask_to_cpus - Takes a bitmask of CPUs and returns a
list of CPU numbers. (i.e. `bitmask_to_cpus "f"` -> 0,1,2,3)
b.) cpus_to_bitmask - Takes a comma/space or range list of CPUs and returns
a bitmask.
Example:
`cpus_to_bitmask "2,3"` -> c
`cpus_to_bitmask "0,1,2,3"` -> f
`cpus_to_bitmask "1,3"` -> a
With or without quotes
`cpus_to_bitmask "1 3"` -> a
`cpus_to_bitmask 1 3` -> a
2.) Added UCI options:
enable - to enable/disable the script from running. [default 1 (on)]
enable_log - to enable/disable logging output to `logger`.[default 1 (on)]

3.) Added `uci-defaults` script `15_smp_affinity` to configure defaults
options on first boot.
