We should have different tiers of books having bigger and bigger line limits, And creative books with infinite lines

Why we need this: if you want to use the terminal module in any way useful you would need way more lines than tis-3d currently has to offer
Why is that? because they let you type strings instead of numbers

Another good suggestion:
#156 - #DEFINE for macros

Sorry, not planning on going that route. A recent PR added the option to disable the line limit in the config, however, maybe that'll help.

note: you can use more then 20 lines
if you use a vanilla book
