Use the BIP173 format, which is whole-word selectable, markup safe, and case insensitive. AGE-SECRET-KEY-1FPSHVEFQXYSX5MMFDE6ZCGRTV4JHQGRFWSS8WETVDSSX76TVV4JQU272CR See https://groups.google.com/d/msg/age-dev/UAjkvLoCr9I/l4Q1h3OPAgAJ. All bech32 Go packages have funky APIs, internal types, or case handling, so include a heavily refactored version of the reference implementation, and the tests from github.com/btcsuite/btcutil/bech32.
