Switch logging to use spdlog and fmt

[EmilDohne]

The PhotoshopAPI was initially made with a custom logging implementation which isn't particularly good or flexible, neither is it standardized.
A goal would be to upgrade this to use spdlog instead which is based on fmt making our logging more robust, less error prone and less macro reliant.

As this is a rather large undertaking this will be put on the backlog for the time being but feel free to contribute if you find the time!
