9b77a887 - Disable color output when redirecting stderr (#742)

Disable color output when redirecting stderr (#742) I'm still confused about it, but this seems to do the right thing? `HierarchicalLayer` internally has [`let ansi = io::stderr().is_terminal();`](https://github.com/davidbarsky/tracing-tree/blob/fcd9eed2528e41cd776b19b9ba45d338ae62a5fc/src/lib.rs#L74), so the logging itself is already correctly uncolored, but errors in the log weren't. Test command, ran with network deactivated: ```shell RUST_LOG=debug cargo run --bin puffin -- pip-compile -v ./scripts/popular_packages/pypi_8k_downloads.txt 2> log.txt ``` **Before** ``` error: Request error: error sending request for url (https://pypi.org/simple/apache-airflow-providers-dbt-cloud/): error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: error sending request for url (https://pypi.org/simple/apache-airflow-providers-dbt-cloud/): error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: failed to lookup address information: Temporary failure in name resolution ``` **After** ``` error: Request error: error sending request for url (https://pypi.org/simple/fissix/): error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: error sending request for url (https://pypi.org/simple/fissix/): error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: dns error: failed to lookup address information: Temporary failure in name resolution Caused by: failed to lookup address information: Temporary failure in name resolution ```
