(core) Currency from grist column is persistent when exporting to excel

Summary:
- when grist table is exported, currency is check and introduced in cell format in the form of "[currency symbol] [value]" (for example: zł 10000, $ 5000) . It's not what some cultures should display currences, but it's close enought
- when no symbol is defined for the currency, currency 3 letters code is used instead
- when currency is unknown, we are falling back to "$"

Test Plan: - nbrowser test scenario added for that purpose, please check Currences.xlsx to see output format exported.
