dirbaio: thanks, now its showing soething more human readable:
```
0.008286 INFO  set up i2c
└─ i2c_blocking::____embassy_main_task::{async_fn#0} @ src/bin/i2c_blocking.rs:51
0.008736 INFO  init mcp23017 config for IxpandO
└─ i2c_blocking::____embassy_main_task::{async_fn#0} @ src/bin/i2c_blocking.rs:56
```
