Usage:

kctx := kong.Parse(&cli, kong.Configuration(kongtoml.Loader, ".app.toml", "~/.app.toml"))

Mapping is achieved by normalising both flags and configuration entries to hyphen-separated keys.

eg. the flag ftl init go --no-hermit will be mapped to the configuration key init-go-no-hermit = true, with fallback to no-hermit = true.

TOML sections are prefixed to attributes via concatenation with -. eg.

["init go"]
no-hermit = true

Will be mapped to init-go-no-hermit = true
