Missing 'pkg_resources' requirement

[nicoddemus]

Hi,

Seems like tracerite imports pkg_resources explicitly:

tracerite/tracerite/html.py

Line 1 in 4417b70

import pkg_resources

For that reason it should declare its dependency on pkg_resources explicitly, I believe:

tracerite/setup.py

Line 20 in 4417b70

install_requires = ["html5tagger>=1.2.1"],

This issue was found during the build of sanic for Python 3.13:
