Mas i340 doublel3 d31 (#347)

* Double size of L4 files

And double max efficient size of leveled_ebloom

* Revert penciller shape

But expand file size at L3

* More concise version

Following code review

* OTP 24 dialyzer fix

Bindings intended to match - so don't use underscore

* Allow eqc tests to work from `rebar3 as eqc shell`

Then `eqc:quickcheck(leveled_statemeqc:prop_db()).`

Plus markdown tidy
