Sbit me0 reg rework
Resolves issue #59 (closed) - Coherence between the GEx/1 and ME0 S-bit registers
Reworking of me0 sbit registers to match more closely that of GEx/1.
Changed registers to SBIT_ME0.OHx.CNT.xxxx
-RESET
resets sbit counters
-SBIT_CNT_PERSIST
controls counter persist, if '1' then counter needs manual reset
-SBIT_CNT_TIME_MAX
controls time for which counter accumulates before updating count register. Default set to 1 sec, so counter displays Hz.
-CLUSTER_COUNT
