Add script for merging zarr files and returning zip files.

Thank you for the update! Could you please check the following codes?

for corr in (DATA / "correlator").glob("*")

It will extract all files in the correlator directory (both .zarr and .dist.zarr).

correlator.convert(corr, overwrite=True)

Do we still need this?

Thank you for your comment!

• I thought I was using NAME_FMT_CORR to specify *dist.zarr, but I realized that the for statement loops in vain, so I fixed it.
• I noticed that correlator.convert(corr, overwrite=True)is not necessary.

Thank you for the update. One more thing I noticed is that the path of the power meter Zarr specifies not a concatenated one but a specific measurement? If it is OK, please let me know and I will approve your PR!

Thank you. Power meter zarr WP7.6_2022144230000.zarr includes all time data, so there is no problem.
