Plus Equals is results in parse error

[TwitchBronBron]

The += operator is valid brightscript, but this library results in a parse error. Take the following code example to show this issue.

var brs = require('brs');
let lexResult = brs.lexer.Lexer.scan(`
    sub Main()
        num = 1
        num += 2    
    end sub
`)
let parseResult = brs.parser.Parser.parse(lexResult.tokens);
if (parseResult.errors.length > 0) {
    throw new Error('There should not be parse errors');
}

Thanks for opening this — I’ve meaning to do it! This is going to be a pretty high priority once I get location tracking finished off.
