shapefile WIP for comment

you could try playing around with ```org.apache.commons:commons-csv```:
```
val parser = CSVFormat.newFormat(',').withQuote('"').withEscape('\\').withIgnoreEmptyLines(true).withCommentMarker('#').withIgnoreSurroundingSpaces(true).withSkipRecordHeader(???notsure).withRecordSeparator('\n')

parser.parse(reader).getRecords.map{ //convert to SF here } 
```
