Sometimes I get an invalid response when calling `_get_gmw_from_bro_id`

When I run

from hydropandas.io import bro
bro._get_gmw_from_bro_id(bro_id = 'GMW000000020882')

I get the following invalid response about 20% of the time. When I retry I get a valid response.

According to this post it is most likely that there are too many open connections to the database service. I build in an automatic retry now but this might become harder in the future.

fixed for now by retrying automatically
