erasure_layout: Add an option to sacrifice unchanged blocks for speed

Someone may prefer to sacrifice sub-blocks needless to change within a
larger erase block for programming speed. These people who are okay to
fry their chip sooner can set this option. If the percentage of
sub-blocks needless to change within a larger erase block is lower
than the given value, the whole larger erase block will be erased.
