add debug log for failed provider calls

[zeroXbrock]

Motivation

If an RPC error occurs, we want to log it with max detail.

Solution

• debug! call in provider when it receives an error from self.inner.call

To see all debug logs, set RUST_LOG=debug in your environment:

RUST_LOG=debug cargo run -- spam ./scenarios/simple.toml --tps 100

Restricting debug logs to contender_core crate:

RUST_LOG=contender_core=debug cargo run -- spam ./scenarios/simple.toml --tps 100
