Looks like a debugging statement was left in

Can this line replace the lines above?

Yes, there was a typo here having lambda instead of Lambda that I forgot to return to and fix.

May be worth implementing an exponentially growing size to get the number of calls to mremap to be logarithmic in the buffer size rather than linear.

Should be experimented with before implementing.

This work aims unify YGM send and recv buffers to the same data type. Previously we were using both
std::vector<std::byte>andstd::array<std::byte>. The goal is to create a sparse, dynamically resizable array. This is needed when many YGM communicators are spawned. This is to avoid fully allocating each of the overly large recv buffers until they are utilized (an issue we found with std::vector).I tried to emulate most of the common std::vector API functions we were using, we should be able to add additional functionality on top of this approach when needed.
I did include a simple test file for CI and unit tests, it may not be fully exhaustive, so reviewing would be good.
