Cataclysm-dda: Allow the magnifying glass to correct hyperopia.

[kwl01skz]

Is your feature request related to a problem? Please describe.
My grandmother can use a magnifying glass to correct farsightedness (FIX_FARSIGHT) while reading, but @ can't.

Describe the solution you'd like
When reading and making, if there is a magnifying glass around, it is allowed to use it automatically to correct the hyperopia.
This requires more code to be added.

Describe alternatives you've considered
Give the flag of the magnifying glass FIX_FARSIGHT and make it wearable.
This only needs to modify little json, but it is a bit silly.

Interesting! I wonder if someone could add a recipe where you can make hyperopia glasses from two magnifying glasses, lol

This ideally should work, but would impose a significant learn speed penalty.

And/or slower read speed, since you'd have to read each line with the magnifying glass
