Provide offline support for approximate slur replacement about uli HOT 4 CLOSED

@mlkorra
I have some doubts for you. Is there a reason you are using https://github.com/maxbachmann/Levenshtein and not https://github.com/ztane/python-Levenshtein. The Latter one seems more popular and also seems to have wheels(which are needed by pydiode to produce web assembly code)

If we can get identical results by using python-levenshtein, lets use that because that might make it easy to compile to webassembly.

You can also try reading this doc - https://pyodide.org/en/stable/index.html
The Using Pyodide section should help.

@dennyabrain Levenstein uses the same code base from python-Levenstein,but the latter is currently not being maintained

i see. @mlkorra can you confirm for me if replacing Levenstien with python-levenstein changes the result?
Since this is the type of core library that does not require constant improvements, its possible that the unmaintained status is not a problem as long as the functionality is the same.

If we can use python-levenstein(which uses C and has wheels available for it), we might be able to compile it to web assembly and use in the browser easily.

@dennyabrain Alright, will work on that and let you know.
