Additional SQL data access libraries

Hi,

There are two libraries to access SQL databases in SQL that might be worth adding in the 'ORM and Datamapping' section:

* Yesql: https://github.com/lpil/yesql
* Ayesql: https://github.com/alexdesousa/ayesql

Also wanted to add: this repo is a great job! I'm browsing it regularity
I have 2 suggestions
1. for each entry add when was the last update of the repo (some are very old)
2. add a section with the new additions since the last update

congrats!
