Add incident proton data class

[jiankai-yu]

I'm adding incident proton data class for the library conversion from ACE to HDF5. In the code implementation, it is almost a replication of the incident neutron data class with a modification in file name suffix (1001.00h).

In addition, I added a function to include stopping power or traverse range just in case they are needed for the transport purpose.

Feel free to let me know if you have any comments.
