dome_key_state_load_map_group(): Get rid of error chain on parse

Since 'combine' errors aren't included in our error chain, calling
`chain_err()` only printed the message inside, not the parser error.

The trouble is, we can't add 'combine''s error to 'error-chain' because
it needs a lifetime:

    combine::Easy::Errors<char, &str, SourcePosition>

and you can't use errors with lifetimes in 'error-chain'.

Since we can't use 'error-chain', just use the 'combine' error directly.
This doesn't allow us to chain an addiitional error message, but does
correctly print the parse error message.
