Example should be renamed to include simpletest

[kattni]

Example miniesptool_esp32multifile.py should be renamed to miniesptool_esp32multifile_simpletest.py to fit with CircuitPython library standards.

In this case, the examples are really not "simple tests" they are used to load code to the esp32 module. A user should not run this to "see how it works". Is "simpletest" really the appropriate name?

[kattni]

@jerryneedell Perhaps not. I guessed. What would be considered a simpletest for this library?

[jerryneedell]

I'm not sure there really is one. It would be like having a simpletest for a .uf2 file. If you run it , it will write the file to your board.

[kattni]

Fair enough. Closing this issue. I think we should consider figuring out what would be considered a simpletest for this lib though, if at all possible.

perhaps @brentru would have some ideas -- this may fit into his guide for the esp32spi...
