Interface{} to modbus-compatible slice conversion

[andreapicaro]

Hello,
is there any example of how to convert from an interface{} to a writable slice of bytes respecting modbus type and endianness.
I was able to find the opposite (from byte slice read from modbus to interface{}) in telegraf code. Now I shall implement the opposite API for writing into modbus and all that conversions appears tricky.

Thanks
