Refactor plot buttons

[tiagofilipe12]

This PR refactored the functions associated with all plot buttons and implemented a sort button for alphabetical order.

It still lacks a way to sort by descending order of values. This needs a way to sort a list using a array with repeated entries. Example

// starting array
array = [a,b,a,b,c,c,d,c]

// final desired array
finalArray = [c,c,c,a,a,b,b,d]

Now, descending order sorter is implemented for all plots but length plot (because it is not a categorical value but rather a continuum of values). Perhaps sorting length values does not make much sense and buttons should be hidden to avoid unnecessary overload.

Also, PR fixed the behavior of reset-sliders and taxaModalClear buttons.

TODO:

• Check sort length plots (maybe there is no point in doing so).
• Implement a loading information for plotly graph generation.

Fixed length plots sorting and greatly increased the speed of sorting plots by storing a list instead of querying again.
