neo.get_io fails on file yet to be written
**Describe the bug**
Calling neo.get_io no longer works with the name of a file yet to be written
which means it can no longer be uses before a 
io.write(... call

**To Reproduce**
import neo
neo.get_io("tobewritten.pkl")


**Expected behaviour**
return an io

**Environment:**
 - OS: [e.g. macOS, Linux, Windows]
 i think all but found with linux
 - Python version
 found with 3.11
 - Neo version
0.12.0
Worked in neo 0.10
 - 
 - NumPy version
not relevant

**Additional context**
our workaround is
def get_neo_io(file_or_folder):
    try:
        return neo.get_io(file_or_folder)
    except ValueError as ex:
        # As neo.get_io only works with existinf files
        _, suffix = os.path.splitext(file_or_folder)
        suffix = suffix[1:].lower()
        if suffix in neo.io_by_extension:
            writer_list = neo.io_by_extension[suffix]
            return writer_list[0](file_or_folder)
