1502	Low bit-depth encoding fails due to the check in riceStatReset	tsukuba.takeshi		"As in the adopted text in JVET-W0178, the StatCoeff[idx] is initialized as below:

- If sps_persistent_rice_adaptation_enabled_flag is equal to 0, the values of StatCoeff[ idx ] for idx ranging from 0 to 2, inclusive, are initialized to be equal to 0.
- Otherwise the following applies:
  StatCoeff[ idx ] = ( 2 * Floor( Log2( bitDepth − 10 ) )	(X)

But in the the riceStatReset function, the initialization takes care of only the latter case (sps_persistent_rice_adaptation_enabled_flag==1). As a result, the following check in the riceStatReset prevents anyone from using 8/10 bit coding regardless of using high bit-depth or not.

{{{
  CHECK(bitDepth <= 10,""BitDepth shall be larger than 10."");
}}}


A fix is to align SW with Spec. i.e.
- Add an initialization process for the case of sps_persistent_rice_adaptation_enabled_flag == 0 in riceStatReset.
