Add more pre-commit hooks

Hooks added:

* check-merge-conflict - checks for files with merge conflict strings
* check-toml - attempts to load all toml files to verify syntax
* check-yaml - attempts to load all yaml files to verify syntax
* end-of-file-fixer - ensures files end in a newline and only a newline
* mixed-line-ending - replaces mixed line endings with LF
* trailing-whitespace - trims trailing whitespace
* python-check-blanket-noqa - enforces that noqa annotations always
  occur with specific codes

Changes made to comply with new hooks:

* Remove trailing whitespaces
* Remove some useless noqa annotations
* Specify errors for noqa annotations
* Add missing newlines at end of files
