Add XLOOKUP without support for non standard match_mode and search_mode - and returning values/arrays instead of ranges

[selimyoussry]

Context

Per this discussion it seems like XLOOKUP is useful to a bunch of people. It is to for me at the very least :) and so I am happy to contribute to its implementation!

How did you test your changes?

I have tested the XLOOKUP implementation against the examples from Microsoft's official doc

• [x] Example 1: should find value in simple column range
• [x] Example 2: should find row range in table
• [x] Example 2 transposed: should find column range in table (official example 2, transposed). This makes sure both column and row search work.
• [x] Example 3: should find use if_not_found argument if not found
• [ ] Example 4: current limitation of this implementation, the approximate match and non standard search are not supported. I added these limitations to the documentation. Hence, this example is not tested against.
• [x] Example 5: nested xlookup function to perform both a vertical and horizontal match (official example 5)
• [ ] Example 6: two nested xlookup + sum (official example 6). I wrote the code but then realized that (based on my shallow understanding of Hyperformula, please correct me if I am wrong), Hyperformula does not support functions returning ranges, only functions returning values.

Thank you again for your input, @selimyoussry, and for spending your time improving HyperFormula. I'm glad to see the new function added in HF v3. Thank you!
