Changed the code slightly to work with Python 3.x and Indigo 2022.1

The plugin failed since Buienradar changed its way of working. Instead of giving integers in the range of 0..255 for the amount of rain the coming 5 minutes it now also show decimal numbers. Since these numbers are in the Dutch local format, where the comma is seen as the decimal point, the plugin's conversion from string to value fails. By changing "," into "." before the string-to-number conversion the problem is solved. Many thanks to https://github.com/mjj4791/python-buienradar/pull/13 which shows a similar issue for another home automation systems plugin.

Next to this bug resolution also added the wind direction in degrees in the device statuses windrgr, d0windrgr, d1windrgr and d2windrgr for current, today, tomorrow and day after tomorrow's wind direction.

Removed a bug which caused double counting the rain amounts in the buienradar part. Also added devicestates for the 10, 60 and 120 minutes interval. In this way you can for example have Indigo trigger you if the next 10 minutes the rain amount is greater than your minimum set. Special thanks to John for his test work.

the datetime function call was not implemented properly

After local testing this is the first release of this plugin I am sharing with the public

Tested with Indigo 7.5
