Allow querying custom properties

[PVince81]

Nextcloud for example has additional properties (like checksum, tags, comments, etc) that can be queried with PROPFIND optionally and are not part of the default response.

The methods stat and getDirectoryContents should allow modifying the properties list to be queried.

Requires namespace support: #210

This will likely have an impact on the current parsing and would need a decision about how to return namespaces (ex: using clark notation).

I like this idea. I would happily entertain contributions regarding both the namespace support and custom properties.

I haven't yet seen a great example of where namespacing is useful or even present (multiple namespaces).

Hey, it used to be possible on 3.x.x https://github.com/nextcloud/viewer/blob/0208dd519d0f266b309d765a73c0221a9d2dd8ee/src/services/FileInfo.js#L33-L61

But with latest 4.x.x it doesn't work anymore @perry-mitchell. Any insights?

Ah, it's becaused you removed the data parameter forward in

webdav-client/source/request.js

Lines 62 to 64 in 6880382

	if (methodOptions.data) {
	requestOptions.data = methodOptions.data;
	}

webdav-client/source/request.ts

Line 19 in edee122

export function prepareRequestOptions(

That is a crazy breaking change,this breaks almost all of our Nextcloud uses of this webdav library :)

@skjnldsv I wasn't aware anyone was using the library like that - else I would have avoided such a change. That is kind of why the customRequest method exists - or at least so I thought :). In the linked example you're passing a fair amount of custom data to the stat call - If these were common use-cases I'm surprised someone hasn't contributed them to this library as a core method or feature.

I'll reintroduce this functionality now.

@skjnldsv Sorry for the inconvenience.. I'll document this better now so it won't mysteriously disappear again.

I've added it back in v4.2.1. You can see it documented in the method options in the readme. It's available under the data property in the options argument for stat (and other methods).
