Converting property values using json.loads

[lyralemos]

I have a small problem with feature properties from imported shapes.

The from_shapefile function tries to use json.loads to append the property value and fallback to the actual value in case of failure.

django-geostore/geostore/import_export/imports.py

Lines 49 to 55 in 4dc40a0

	for feature in shape:
	properties = {}
	for prop, value in feature.get('properties', {}).items():
	try:
	properties[prop] = json.loads(value)
	except (json.JSONDecodeError, TypeError):
	properties[prop] = value

This is fine except that, if have a string property with only numbers json.loads will change it to integer as this example:

>>> a = '123'
>>> type(json.loads(a))
<class 'int'>

I guess this is not ideal for cases that depend o the property type to be precise, as mine is.

Wouldn't be a better approach to store properties as they came from fiona?
