StencilClient configured with ondemandRefresh doesn't refresh for nested protos #77
Description
Describe the bug
Stencil Client when configured for ondemand refresh it uses ProtoParserWithRefresh which checks for any unknownfields and refreshes the cache, but unknownfields does check only in the root proto, so for nested protos if there are new fields being added it won't refresh the cache.
To Reproduce
Create a proto & add a new field at a nested level or modify an enum this should be reproduced in that case while deserializing
