html viewer

Hi

This is not a bug, it is just to tell what I did. I have developed a simple way to inspect the list of CRS, including finding the EPSG equivalent when an ESRI one is deprecated.

It is taking the data directly from `projection-engine-db-doc` repository, so it is "automatically up to date". The code there is just HTML and JavaScript to parse the JSON files.

It is implemented in this repository: https://github.com/jjimenezshaw/Esri-codes-analyzer
In particular, you can see it in action in https://jjimenezshaw.github.io/Esri-codes-analyzer/deprecated.html and https://jjimenezshaw.github.io/Esri-codes-analyzer/not-deprecated-esri.html

I hope it is useful. Maybe other kind of "queries" can be done as well. The idea is that searching in the web page is fast and easy. It does not try to have a form or anything else complicated.

Cheers.
