Support more field types for dbase IV

I tried opening a dbase file that had a Float column.
Here is the error:
Fatal error: Uncaught org\majkel\dbase\Exception: Format `dBASE III PLUS` does not support field `F`

I can try adding it myself and see if I can get it working.
If I get it working can I upload a version that works with floats?
What other fields should be supported?
Others I see on https://www.dbase.com/Knowledgebase/INT/db7_file_fmt.htm
Long, Double, Binary
I am not sure which one of these I will need for my project.
