   This PR bumps the Sidecar version to the current latest HEAD of Sidecar. 
Bumping the version surfaced an issue in the LZ4's implementation of the 
XXHash32 hash value. The hash value is not masked and this causes the negative 
sign to be forwarded producing the incorrect hash result. Other 
implemnentations correctly apply the mask to the produced value (i.e 
commons-codec).
   
   We do not consider switching to `commons-codec` because Spark has a 
dependency of codec, and in older versions of Spark (2), the XXHash32 
implementation is either non existent or the APIs have changed.
