Update of libraries

Some libraries were at the beginning of my XOD experience, they had errors or they were not useful they only helped me to learn. That’s why I removed them from the list.

I have created one for the examples only, in order to leave in each library only the nodes and a list at the beginning 00-list … where the corresponding nodes will be, to identify them or copy and paste them in the new patch.

Example library cesars/0-all-examples

Library cesars/tm1637 and library cesars/rich-uno-r3 for kit Biomaker

There are two libraries for TM1637 for different applications, the DFPlayer and IR-remote libraries are not finished.

Thanks Matt (for the tests), Jim, Alex and Pia for the kit. (which will arrive soon)
