Loading a model form a memory buffer

[8-byte]

Hello everyone,
I have a use case where a frozen graph is stored in an encrypted file. I decrypt the file to a memory buffer and need to create the model from that. I'm thinking that the way to implement this to add a cppflow model constructor that takes a character pointer and a size. I have two questions: 1) would this be the correct approach? 2) is this something that should be part of cppflow master (@serizba)?
Please let me know.

Another way would be to add another mode::TYPE that can be passed into the current constructor but the naming of the types would need to be reworked for clarity.
