pw_StatusString was switched to a series of if statements rather than a switch to compile with -Wswitch-enum. Unfortunately, some compilers (including arm-none-eabi-gcc 10.3 and earlier) do not optimize the if version of the function very well, resulting in a substantial code size increase. This function replaces the if statements with a swtich. It includes the internal-use-only enum case for -Wswitch-enum compatibility.
