Taxjar Failing for too many requests

[romancristinel]

When taxjar service fails with Error code 429 (possibly others) the exception is not handling the data properly:

https://github.com/taxjar/taxjar-php/blob/master/lib/TaxJar.php#L37

There are no error and detail properties, therefore the taxjar-php library throws a weird exception ("Trying to get property 'detail' of non-object")

Thanks @romancristinel for reporting this. We're looking into addressing it in a future version.

Our API should now return a valid JSON error response for 429 errors with error and detail attributes included. Thank you!
