2.1.0: Conversion function improvements, better error handling, README updates

• Implement from_map/1,2 and as_map/1 functions; these work similarly to the from/as_proplist suite.
• Improve from_proplist/1,2 converter:
  • Only extract the format from Opts input one time instead of N times.
  • Stop converting keys to binary: This makes the function work more similarly to from/as_map, which doesn’t transform keys (allowing us to modify maps using maps:map/2 instead of maps:fold/3)
• Improve guards and error outputs on unexpected inputs in a number of functions throughout the library: more consistent badarg errors instead of case_clause, function_clause, etc.
• Add README examples of conversion functions
• Fix README examples overlooked in change to map as the default format.

2.0.0: Erlang 18+, maps by default, etc.

• New default format: map
• Remove compatibility with Erlang 17 and below.
• Remove encode/decode functionality (no more jsonx dependency)
• Remove key sorting functions
