QVM updates:

• The QVM allows the user to specify a preference for memory allocation handled by a foreign operative rather than allocation on the Lisp heap. One of the main uses for this is to allow users to easily exceed the 10 GB memory limit in the standard shipped QVM-APP binary.

QVM-APP updates:

• Two new endpoints were introduced: the PROBABILITIES endpoint, which returns a probability distribution rather than the full output of density matrix simulation, and which cuts down transmission cost from 4^d to 2^d; and a RUN-FOR-EFFECT endpoint, which applies instructions to a QVM without resetting the state of the QVM before or after, for incremental application of instructions.
• QVM-APP now checks for the availability of SDK updates on launch, so that users remember to upgrade when an upgrade is available.

Small bugfix: match the name change from quil-lang/quilc@d771b41 .
