Filter out TrigPassBits, 1st pass on features based compression
This MR has two parts:
- ignores TrigPassBits when comparing FEA vectors (increases chance of mergin)
- has 1s attack to merge ConvProxies that have features (basically factor of 10 reduction of number of conv proxies) By default, the compression is off by default no to to interfere with the conversion of ConvProxies to IM / H that is the critical piece.
