feat: Abstract Logger and simplify code (#1207) 
* Logger: Rename logger to Logger from dLogger

* Logger: Add compile time filename

Fix include issues
Add writers
Add macros
Add macro to force compilation

* Logger: Replace calls with macros

Allows for filename and line number to be logged

* Logger: Add comments

and remove extra define

Logger: Replace with unique_ptr

also flush console at exit. regular file writer should be flushed on file close.

Logger: Remove constexpr on variable

* Logger: Simplify code

* Update Logger.cpp
