Got <BV> to stop showing up in LMP deps

[reecelikesramen]

Fix for #287

• culprit is Black formatter adds space after # comment
• it doesn't always though because if the formatter raises exception, no format
• fixed by chaning #<BV> => # <BV> but for all tags

NOTE: this might not be the right way since without rerunning all the LMPs, the old source persists in the DB, so the old # tags won't get rendered right in the React app. Could instead enforce that # becomes # even after formatting, or strip out the delimiter before formatting and add it back in after.

Something else less important I noticed while working on this had to do with recognizing imports as dependencies. In __testing__.py one of my LMP's has an Optional[str] as a parameter type so it depends on from typing import Optional. However, in ell-studio that dependency resolves as from typing import _UnionGenericAlias probably due to how the lexical analysis works since Optional inherits from _UnionGenericAlias

Before:

After:

In DiffRenderer.js just filtering these out of the code and previousCode:

function removeEllTags(code) {
  const ellTagRegex = /\s*#\s*<\/?(BV|BmV|LMP)>/g
  return code.replace(ellTagRegex, "")
}

code = removeEllTags(code)
previousCode = removeEllTags(previousCode)

i think we dont want to remvoe tags. but if this is only for the diff renderer i guess thats fine ;)
