Enumerable filters project

[deanmarcussen]

This introduces a Enumerable filters project which allows projecting an enumerable into a Filter Parsing arrangement, much as we can do with an IQuery currently.

Filtering on an IEnumerable is useful, for the case where we are using a single SQL document, i.e. like a TemplatesDocument where the items we want to filter on are contained in a dictionary, or list.

You may or may not want this in the YesSql project :) but I'm using it internally, so figured it was worth pushing up somewhere.

Note: There seems to be a slight bug in Partlot compilation which is causing the tests to fail randomly. I assume it's related to initialization, when initializing in parallel. Only applies to complied parsers.

I'll open an issue there to go with

@sebastienros Can you give a review for this one?

[sebastienros]

@copilot add a README.MD at the same level as the new project (not the tests) describing its goals and usages.

@deanmarcussen There is a compilation bug with this one. I fixed it locally. Want me to update your branch?

[deanmarcussen]

100% @Skrypt

I don't have access to this repository to commit directly to a branch. I will need to create a fork which is odd.

Here is a screenshot of the fix I did locally after merging latest main branch on top of your branch.

ok, probably just due to a change in Parlot, I'll try and make time today to pull and do the same fix

@sebastienros While I can't promise that a PR will be done shortly for Orchard Core to show usage of this feature. Can we merge it for a future release still? I believe we need to merge this first anyway. Else, I need to keep that code in a custom module in OC.

Here is the related WIP branch: https://github.com/OrchardCMS/OrchardCore/tree/skrypt/shortcodes-filter
