Adding ZFP version 0.5.1 and variant for uint8 bit stream word type (#3753)

Browse Source 
* adding 0.5.1 and variant for uint8 bit stream word type

* Revisions as per davydden

* fixing style (flake8) issues

* - switched to derive from MakefilePackage
- fixed typo in variant check
- Confirmed installs correctly with bswtuint8 variant

* added build method; changed zfp_incdir to incdir
