feat: Add Netbox User Permission Resource

This feature allows management of netbox user permissions with
terraform. It follows the pattern of testing and design similar to that
of other resources.

A unique feature of this resource is the handling of the `constraints`
field. Since this field is a JSON blob in the netbox API, we had to
find a nice way to convert a JSON string into a JSON blob. And since
this field can be either a JSON list or a JSON object, we had to handle
this accordingly. By using `json.Unmarshal()` on the string, and then
doing a type switch, we could detect the correct type, and set that in
the struct for sending it to the API.

+## Schema
+
+### Required
+
+- `actions` (Set of Number) A list actions that are allowed on the object types. Acceptable values are `view`, `add`, `change`, or `delete`.
+- `name` (String) The name of the permissions object.
+- `object_types` (Set of String) A list of object types that the permission object allows access to. Should be in a form the API can accept. For example: `circuits.provider`, `dcim.inventoryitem`, etc.
+
+### Optional
+
+- `constraints` (String) A JSON string of an arbitrary filter used to limit the granted action(s) to a specific subset of objects. For more information on correct syntax, see https://docs.netbox.dev/en/stable/administration/permissions/#constraints. Defaults to `""`.
+- `description` (String) The description of the permissions object.
+- `enabled` (Boolean) Whether the permissions object is enabled or not. Defaults to `true`.
+- `groups` (Set of Number) A list of group IDs that have been assigned to this permissions object.
+- `users` (Set of Number) A list of user IDs that have been assigned to this permissions object.
+
+### Read-Only
+
+- `id` (String) The ID of this resource.
