Update pest 2.4.0 => 2.7.4 (#304)

## What is the goal of this PR?

We update to pest and pest-derive v2.7.4, which among other things purports to fix the error where [deriving Parser fails on "undeclared crate or module `alloc`"](pest-parser/pest#899) (pest-parser/pest#900).

## What are the changes implemented in this PR?

We also clean up some compile warnings (unused imports and hashes).
