This pull request includes several changes to the benches/bench.mojo file, new benchmarking functions for Decimal.from_int, updates to the mojoproject.toml file, and improvements to the Decimal struct in src/decimojo/decimal.mojo. The most important changes include adding new benchmark cases, updating the mojoproject.toml with new test and benchmark commands, and refining the Decimal struct's methods and documentation.

New Benchmark Functions:

• Added comprehensive benchmarks for the Decimal.from_int constructor in benches/bench_from_int.mojo. This includes performance comparisons against Python's decimal module with 20 diverse test cases.

Updates to Benchmark and Test Commands:

• Updated benches/bench.mojo to include new benchmarks for bench_from_int and bench_root.
• Modified mojoproject.toml to add new test and benchmark commands for test_from_int and bench_from_int.

Improvements to Decimal Struct:

• Refined the Decimal struct in src/decimojo/decimal.mojo by updating method documentation and adding a new copy method and a new clone method.
  These changes enhance the benchmarking capabilities, improve the organization of test commands, and refine the Decimal struct for better clarity and functionality.
