Keyboard Input support for picceler

[Robertkq]

This PR will introduce support for reading from the keyboard, see read_input.pic for a clear example of this.

We currently support two functions, read_string and read_number both supporting a (prompt) argument. Also it removes a lot of code that used to verify that input to ops was constant, as this is no longer the case all the time, but some analysis in when compile time information is presented, that optimizations happen, should be conducted at some point in the future

Also added some QoL improvements to the code

This addresses the #52 issue

Pull request overview

This PR adds runtime keyboard input support to Picceler through read_string(prompt) and read_number(prompt), wiring new Picceler ops through MLIR generation and runtime-call lowering. It also relaxes neighborhood size handling so some image ops can use runtime SSA values instead of only compile-time constants.

Changes:

• Added read_string / read_number ops, MLIRGen support, runtime functions, and an example program.
• Changed neighborhood op interfaces and affine lowering to work with runtime mlir::Value neighborhood sizes.
• Added small QoL cleanups including runtime debug logging via spdlog, an integer constant helper, and .clang-tidy filtering.
