Write XTF example failing to write packets

[Tdarnell]

Following the notebook example for writing XTF data gives the following error when modifying existing XTF packets:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[31], line 14
     12 # Write packets
     13 for packet in packets:
---> 14     f.write(packet.to_bytes())

TypeError: to_bytes() missing required argument 'length' (pos 1)

It seems the to_bytes method being used in builtins.pyi requires the following: length: SupportsIndex, byteorder: Literal["little", "big"]

this problem seems to come from my XTF files containing the following packets alongside sonar:

XTFHeaderType.navigation
42
XTFHeaderType.attitude
3
XTFHeaderType.sonar
0

I would like to modify the original data file then save a renamed copy, including these additional packets.

It's been a while, but are you able to provide a small snippet that illustrates the problem?
