[nongnu] elpa/csv2ledger 0af0aa3de2 021/190: Rename `c2l-parse-date` and update doc string.

[ELPA Syncer]

branch: elpa/csv2ledger
commit 0af0aa3de218ce82bc74ea178578ab912e78f657
Author: Joost Kremers <joostkremers@fastmail.fm>
Commit: Joost Kremers <joostkremers@fastmail.fm>

    Rename `c2l-parse-date` and update doc string.
    
    New name: `c2l-convert-little-endian-to-iso8601-date`. It's a mouth full, 
but it
    better represents the function's purpose.
