jprq go client with --host option

Added --host flag to connect with custom jprq server
same functionality as the jprq-python-client implementation.

• build-client.sh builds all the client binaries. Copy and run a line to only build for that arch.
• build-http.sh builds all HTTP Server binaries
• build-tcp builds all TCP Server binaries

This release contains the client (in jprq-linux-*) and two server (http in jprq-http-linux-*, tcp in jprq-tcp-linux-*) builds for linux (amd/x64, arm, arm64)
