Can you change this to a concrete example?

Extracts the file descriptor loading part from
prost_build::compile_protos()to a newprost_build::load_fds()function.This allows inspection or even modification of descriptors before calling
prost_build::compile_fds. Possible use cases include generating additional files from the descriptors, or set computedConfigattributes by introspecting what is actually present in the.protofiles before generating the code.
