[BUG] Outdated/typo in requirements.txt

[johnygomez]

Description

It seems current requirements.txt is either outdated or contains a typo in https://github.com/plasticityai/supersqlite/blob/d74da749c6fa5df021df3968b854b9a59f829e17/requirements.txt#L1 When trying to pip install lsb-db==0.6.4 I get following error

Could not find a version that satisfies the requirement lsb-db==0.6.4 (from versions: none)

I guess this could be a typo for lsm-db?

Expected behavior

Installing this package via pip won't fail

System

Ubuntu 18.04LTS / Python 3.6 / pip 19.1.1
