Improved Formula Engine

* Does not try to forcefully cast column content to float
* Silences any errors during formula evaluation, you can look at
  `v:errmsg` to see if there was any error during the evaluation for

+  You can highlight cells based on content by setting `let g:table_mode_color_cells` :
+    - cells starting with `yes` will use the `yesCell` highlight group.
