halt-at-non-option is incompatible with unknown-options-as-args

[kherock]

Enabling unknown-options-as-args seems to short-circuit the code that would set notFlags to the remaining arguments after checking if halt-at-non-option is enabled:

yargs-parser/lib/yargs-parser.ts

Lines 225 to 226 in 0fdbfa1

	if (arg !== '--' && isUnknownOptionAsArg(arg)) {
	pushPositional(arg)

I see several instances where isUnknownOptionAsArg is guarded with a basic check for /^-/.test(arg). Would it be naive to suggest that updating the condition to arg !== '--' && /^-/.test(arg) && isUnknownOptionAsArg(arg) should fix it?
