Terminal CLI requests not shown, even if HTTP_PROXY is set

Proxyman version? (Ex. Proxyman 1.4.3)

1.23.0

macOS Version? (Ex. mac 10.14)

10.15.4

Steps to reproduce

1. Open Terminal
2. Set HTTP_PROXY environment variable
3. Check output from env to confirm environment is set correctly
4. Run a command-line tool that makes an HTTP request (e.g., tabix)

As an example command:

$ HTTP_PROXY=http://127.0.0.1:9090 
$ env | grep HTTP_PROXY
HTTP_PROXY=http://127.0.0.1:9090
$ tabix http://explore.altius.org/tabix/vA/hg19.15.all.KL.gz chr5:78459198-78643943
...

Other tools also do not seem to work (e.g. curl):

$ HTTP_PROXY=http://127.0.0.1:9090 curl http://explore.altius.org/tabix/vA/hg19.15.all.KL.gz.tbi -o /tmp/foo.tbi

I do know that one can manually set the proxy in curl with the -x option. However, I'm trying to demonstrate that HTTP_PROXY appears not to work with Proxyman for generic CLI operations.

Expected behavior

When HTTP_PROXY is set, I would expect to see the details of this and other HTTP requests in Proxyman made with CLI tools.
