v1.7.0
A few new features. WithIgnoreUndefined is a new option that allows parsing to continue if a flag is specified but not defined in the flagset (thanks @yjp20). WithAllowMissingConfigFile allows parsing to continue if a specified config file doesn't exist (thanks @Dragomir-Ivanov). And package fftoml is refactored to include a WithTableDelimiter option to map TOML tables to flag names (thanks @GeorgeMac).
