[ext.rb] test for BOTAN



[ext.rb]プログラムの中の一行を BOTAN用に書き換えて、わずか 2行(下記$以下)の
ターミナル実行で、前回と同じ地球画像(下半分が奇妙) foo-90.jpg が得られた。

> YOMOGI用 pattern = "4A4736594257304A4736594D58303EF0FFF0FF#{ID}"
> BOTAN用  pattern = "94A662B29AB26094A662B2A0A86103F042CCFF#{ID}"

$ grep 2025-10-13 20251023btn.csv > wip.csv
$ ruby ext.rb 90





ほぼ綺麗な画像。
$ grep 2025-10-29 20251030btn.csv > wip.csv
$ ruby ext.rb DC
