Parse Externalizable values from environment variables #158

Closed istathar closed 1 year ago

istathar commented 1 year ago

We previously had queryOptionValue' as a convenience for reading a value (notably numeric values) from a command-line option. This branch adds the a similar convenience for declared environment variables queryEnvironmentVariable'.

Externalize instances for Int8 and Word{8,16,32,64} are added.
