Replace xml2js with fast-xml-parser

[janybravo]

To remove dependency/peerDependency of xml2js that causes problems with VITE. Backwards compatibility with xml2js is preserved by using XmlParserOptions export with API of fast-xml-parse.

As far as I tested, everything works as before. But I would also ask someone else to additionally check.

The things I found out that also don't work on master (published version):

1: Time dimension is in a different place in SH WMS GetCapabilities response - it's not in every layer, but under the parent Layer element in the XML.
So, the WMSLayer.findDatesUTC fails, because it assumes that the time dimension is in every layer (https://github.com/sentinel-hub/sentinelhub-js/blob/master/src/layer/WmsLayer.ts#L69). Probably best to solve in a different MR.

2: WMTSLayer doesn't have the findDatesUTC() implemented, so we "can't test" if the dates are parsed correctly from the WMTS GetCapabilities response.
Getting dates from WMTS GetCapabilities response was implemented in EO Browser directly in the past, and now no WMTS datasources are used, so not needed from our side. Might be useful for others though. Can be solved in a separate MR.

3: EDIT AFTER this commit

The build process now works, but the npm i still changes the package-lock.json file - it removes the part below

      "dependencies": {
        "@rollup/rollup-linux-x64-gnu": "*"
      },

old error

The build process fails for me (on linux) with the error below and the mentioned solution (removing node_modules and package-lock.json) works.
The problem is that after installing dependencies again, the package-lock.json is totally different from before. (happens for both node 18 and 20)
