A gha component example: excel static read and interactive read

Hi group,

I recently started to develop gha component(also using Visual Studio), this is my first version of Excel read component. I know many people has done this before, but I think it is still a good topic to start with.

There are two components: static read and dynamic read. The difference is the dynamic one could monitor excel change and reflect in the output immediately. Both component can read rows or columns or entire sheet, the result can also organized by  rows or columns accordingly. I attached a simple manual for  details.

I attached the Visual studio file, you can tell the structure is messy(first time use VS to to do real stuff), luckily it works eventually. 

I have to say if I also "eat bugs for breakfast" then this simple breakfast takes a bit long...

Any suggestions please let me know.
