fixing DST tag in hashToG1
...
The DST tag should be unique to achieve domain separation
of hash functions as defined in:
https://tools.ietf.org/id/draft-irtf-cfrg-hash-to-curve-06.html#domain-separation
Changed DST tag to one that indicates the PoC status of this code.

using normal file io instead of memfiles
...
mmap has serveral potential issues and we do not really need it, so
changing to use the normal system file interface is better.
