How to update mitmrelay and replay binaries?

[FazleArefin]

proxify release bundle comes with 2 other binaries: mitmrelay and replay. Although proxify has an -update flag the other 2 binaries do not. Executing a proxify -update updates the proxify binary only, leaving the other 2 at their older release.

Please implement -update and -version options for mitmrelay and replay
