Simple-xlsx: updated to 2.0

I rewrite the simple-xlsx completely, it's not back compatible.

If you're using this package, want to update to this version, please update simple-xml first.

raco pkg update simple-xml; raco pkg update simple-xlsx

Version 2.0's main feature:

  1. Read and Write a .xlsx file combined into one procedure, means you can modify a .xlsx file as you need.
  2. Simpler usage, can set all the common styles.
  3. Faster.

If you encounter any bug or feature request, please let me know.
