During runtime, when we add a new image channel, where are points/spines columns added?

Hi @Suhayb-A

I will just ask the question and fill in with details as needed.

If we have an mmap loaded into memory, say it has one channel.

This gives us points/spines columns corresponding to _ch1_.

Then, during runtime, we add another image channel.

Question: where (if at all) are the new points/spines columns for _ch2_ added?

I see addSchema() when an mmap gets initialized. I do not see where new _ch<n> columns are added when we add a new image channel (during runtime)
