DOLfYN reading a .VEC file indefinitely

[akeeste]

Describe the bug:

@jmcvey3 I'm assisting another user with reading their .VEC file. DOLfYN gets stuck and reads it indefinitely. Other VEC files from this user are read normally.

The issue occurs when _NortekReader.init_ADV() is attempting to determine the code spacing. In code_spacing, the first call to self.findnextid() gets stuck in the while loop, seemingly because the ID it is searching for is never found.

To Reproduce:

ds_adv2 = dolfyn.io.api.read("SANDIA02.VEC"). @akeeste can share the data directly if needed.

Expected behavior:

Run without error, as on other VEC files

Screenshots:

Desktop (please complete the following information):

• OS: Windows 11
• MHKiT Version: v0.9.0

Additional context:

File appeared to be either corrupted or filled with "fill" bytes added during real-time operation. There were two "while loops" that the script became hung up on, and PR #372 added logic to escape these loops.
