Regex for gnis:feature_id allows leading zeros

[watmildon]

Describe the bug
The regex for the field gnis:feature_id allows leading zeros. Previous imports have incidentally had IDs with leading zeros but that has now been corrected.

To Reproduce
Steps to reproduce the behavior:

1. Create an object with gnis:feature_id=00000123

Expected behavior
Warning as this is not proper for a numerical id field.
