Add setting to limit scanned formats

[st-sloth]

Currently, it seems that phonegap-plugin-barcodescanner is trying to scan every "supported" format from the image. In some cases, however, it leads to inability to read the code, while when run with specific format, the scanner can read the code.
Maybe it makes sense to allow the user to limit formats to try to read, like in Barcode Scanners from Cognex?

It's been one year since this request was advised. Any reason it's been one year?
