Add new functionalities including DAG and custom tasksets, support more schedulers, and improve GUI

[CloverCho]

New types of tasksets

• DAG (Directed Acyclic Graph): creates randomized dependencies between reactors (and reactions inside).

  

• Custom : supports user-defined tasksets written in custom LF files. For the purpose of usage, we create a sample taskset which provides comparison between a scheduler with deadline and another scheduler without deadline

  

GUI improvements

Reference: TU Dortmund's framework(link)

Basically, this PR also includes GUI improvements. User can choose

• more schedulers to evaluate
• more types of tasksets: basic, DAG, or custom
• several properties for constructing the tasksets: e.g., number of min/max workers and random seed.

When the user determines properties and clicks the run button, the program will generate several LF files, build, execute binaries, and get information on the total physical execution time and the number of deadline misses. The program will also visualize physical execution time and the number of deadline misses using graphs
