Removes lokimq::string_view (the type alias is still provided for
backwards compat, but now is always std::string_view).
Bump version (on dev branch) to 1.2.0
string_view isn't supposed to be implicitly convertible to std::string
and code would break compiling under c++17 (when our local string_view
is simply a std::string_view typedef).
This separates the dict traversal into `next_...` functions that return
a key-value pair, and `consume_...` that return just the value. The
latter is particularly useful when using `skip_until` to position
yourself at a known key.
This library is adapted from lokid's existing quorumnet code (added in
6.x) used for SN-to-SN communication for quorum voting but generalized
to be usable both there and as a basis for other communication channels
with loki projects (for example: wallet-to-lokid communication; loki-ss
and lokinet internal communication with lokid; loki-ss to loki-ss
communication and message passing; perhaps eventually loki p2p traffic).
This initial release compiles but likely has a few warts and bugs that
need ironing out in the implementation before it is production ready.
Some tests will follow.
