Updated libhydrogen submodule

No other API changes or incompatibilities that I'm aware of

pwhash: use uint64_t for opslimit parameter

Update for go get -u to retrieve this.

v1.0.10 libhydrogen/7bd39c4

Tagging a new version for latest jedisct1/libhydrogen@7bd39c4

Simplified imports to prefer system import.

Note

Some APIs have changed, e.g. hydro_kx_N_PACKET1BYTES is now 48 instead of 32. This would break kx for a client on an older version. Decided to tag as v1.0.10 since there were a few fixes unrelated to these breaking changes that could be pulled in to create releases that don't break anything.
