v0.6.0

Added

• Prometheus metrics for modbus get/set commands

• get_symbols_for_point() which will return the symbols for a given point.

• get_point supports repeating blocks.

Changed

• Adjusted hardcoded 2-address-offset into a const, ADDR_OFFSET. Explained its significance in the code comments.

• Downgraded error! to debug! in situations where we're logging an error and then sending that same text upstream in a Result<T,E>

• changed variable names to avoid rustc errors about unused values (they're part of the testing apparatus and aren't used anyway)

• set accessibility for symbol-related data to full pub

Fixed

• Scale-factor mathematical logic was just... wrong. Fixed it.
