ParserFunction type does not specify options as optional

[patrickroberts]

On line 1322 you have

export type ParseFunction = (input: string, options: IParseOptions) => any

while on line 1004 you have

function peg$parse(input: string, options?: IParseOptions)

Of course, this causes an error when you try to call parse() using only the string argument. The quick work-around currently is to modify the output .ts file to export the correct type, or to call the parse function with an empty object for options, but both of these are undesirable in the long run. Is this important enough to merit a patch?

Thanks @patrickroberts Indeed! Patched and releasing it.
