use blst_p1_add_or_double instead of blst_p1_add 
blst exposes two add functions: one that works for the corner case
of doubling, and one that isn't. It seems safer to use the one that
works, even if it is highly improbable in these cases that doubling
would occur.

speed up tag generation by a factor of s 
Scalar multiplications in tag generation can be rearranged
to benefit from the way random points are being generated.
Since random points are themselves generated using scalar
multiplication and the base is common, the sum of multiplications
becomes a single multiplication with the scalar sum, resulting in
a nice speedup.

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.
