Adds a --max-recv-message-size CLI flag (in MB, default 4) so users can raise the gRPC server limit when the function emits enough desired resources to exceed the default 4 MB cap, which otherwise causes XR reconciliation to fail with ResourceExhausted. Fixes crossplane-contrib#135 Signed-off-by: Christian Artin <gravufo@gmail.com>

Description
Adds a
--max-recv-message-sizeCLI flag (value in MB, default4) that is wired through tofunction.MaxRecvMessageSizefrom the function SDK. This lets operators raise the gRPC server's max receive size when the function emits enough desired resources to exceed the default 4 MB cap.When the deletion-ordering option is used on a sizeable pipeline,
function-sequencercan produce a large desired-state payload. Crossplane then fails XR reconciliation with:This matches the same flag added in
function-template-go#91and aligns with the discussions infunction-auto-ready#47,crossplane#6392, andfunction-sdk-go#194.Behavior
--max-recv-message-size(int, MB, default4) — preserves existing behavior when unset.1024 * 1024and passed tofunction.MaxRecvMessageSize.Testing
