Firestore map keys considered invalid when containing / characters #83
Description
Describe the bug
We often store mappings of document reference paths (as strings) to values inside documents.
e.g.
{
'activityType': 'activityA',
'agents': {'products/product-a': 5.0},
}
Using the native Firestore libraries, we encountered no issues writing Firestore maps inside our documents that contain / characters in the key string. This seemingly is allowed in Firestore documents but triggers the Invalid argument (path) exception when attempting to write a document containing the map using the library.
Invalid argument (path): Paths can't be empty and must not contain '*~/[]'.: "products/product-a"

To Reproduce
await firestore.doc("activities/new-activity").set({
'activityType': 'activityA',
'agents': {'products/product-a': 5.0}
});Expected behavior
This should be a valid document and written to Firestore with the string key "products/product-a" in the document's list of product -> value mappings.
