New storage layout extension NNNN-uri-direct-storage-layout

[alvinsw]

We want to be able to directly map a URI into the storage layout directory.
It may be similar to #57 but simpler and just use the path of any valir URI directly.

Should there be a note about the possibility of many to one mappings created by the idea of regex->string replacement? A warning or advice about what to do in the event of collision?

Is the replacement strictly regex->string or is regex->regex-replacement intended? I ask because later there is a comment about static string replacement which sort of implies there might be something dynamic too

How should multiple replacements be handled? Are the regexes applied in turn? Ie. does [['a','b'],['b','c']] applied to a produce c?

@alvinsw : Is this extension still of interest? There are open questions above.

[alvinsw]

Yes I think the replacement is a weak point here. After discussion with @ptsefton we'll take off all the parameters including the one for string replacement. So the spec should be simpler and straightforward.
I'll push an update soon.

@alvinsw & @ptsefton - Are you still interested in moving forward with this extension or should be close out this PR?

[alvinsw]

We still need the layout option where we can directly map a URI to directory paths without any hashing.
There are some overlaps or similarity with the other proposed extension NNNN-direct-clean-path-layout. However, I couldn't understand the last comment from @neilsjefferies that says it should be amended as an object extension. How can that works? If PR 57 can go through as a layout extension in some form or another then we can merge this one into that.

Thanks for replying @alvinsw . If you are still interested in moving this forward, could you push the update to reduce parameters you proposed in your Aug 9, 2023 #63 (comment).

(We aren't sure whether #57 is going to move forward but anyway the comments from @neilsjefferies do not apply to your use case.)

@zimeon I have updated the document and removed all parameters. Can this be approved now?
