looks like it is blocking and reading 1.6MaB chunks of data at once. I
can hack it to read only 4 bytes.

warning: this script hopefully works but drops chunks due to waiting
on network and not buffering input

The last output data is the root node.

I've started the download and it's caching blocks to try to find the
data. Presently it has to be mined for it to find it.

But, I forgot to update flat_tree. So this isn't actually testing it.

[user@ log]$ pip3 install --upgrade git+https://github.com/xloem/flat_tree@main

[user@ log]$ echo '{"ditem":
["9fHmJ9utcCSAYPVPGUau98J7fl1i-lI9E8TvvQsx6CA"], "min_block":
[1056141, "PvRhlqyLRwsUjkFLL19PYc872olmvDXbgfizaWLzMasIce4tnsg3JILUOuVHFU7U"],

It ran with the new flat_tree !

To give it a little time to consider being mined, I'll ensure the
script actually _uses_ flat_tree and doesn't craft the structure by
hand.

from flat_tree import flat_tree

indices = flat_tree(3) #append_indices(3)

It looks like it's working.
