Minor Changes

• 20b4311:
  • Added the ContractDecoder type
  • Added a function Provider.contractDecoder to retrieve the provider's ContractDecoder instance
  • Changed EdrContext.createProvider to receive a ContractDecoder instance instead of a TracingConfigWithBuffers
    • The ContractDecoder can be constructed from a TracingConfigWithBuffers using the static method ContractDecoder.withContracts
  • Changed Provider.addCompilationResult to no longer return a boolean. Failures are now signaled by throwing an exception.

Patch Changes

• ba6bfa0: Added support for Solidity v0.8.30
• d4806e6: Added a collectStackTraces option to SolidityTestRunnerConfigArgs, specifying what strategy to use for collecting stack traces
