Possibly Circular Import Error in small_time #272

Describe the bug
pixi run mojo package lightbug_http/ fails.

Getting bizaar cannot be converted from 'SmallTime' to 'SmallTime' and cannot be converted from 'TimeZone' to 'TimeZone'

This is giving "circular import issue" vibes.

I'm happy to work on a PR to untangle this.

To Reproduce

pixi run mojo package lightbug_http/ Included from /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/__init__.mojo:1: /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/small_time.mojo:292:20: error: no matching function in call to 'strptime' return strptime(date_str, fmt, time_zone.from_utc(tz_str)) ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Included from /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/__init__.mojo:1: /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/small_time.mojo:243:4: note: candidate not viable: argument #2 cannot be converted from 'TimeZone' to 'TimeZone' fn strptime(date_str: String, fmt: String, tzinfo: TimeZone = TimeZone()) raises -> SmallTime: ^ Included from /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/__init__.mojo:1: /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/small_time.mojo:270:4: note: candidate not viable: argument #2 cannot be converted from 'TimeZone' to 'String' fn strptime(date_str: String, fmt: String, tz_str: String) raises -> SmallTime: ^ Included from /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/__init__.mojo:1: /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/small_time.mojo:448:32: error: invalid call to 'format': method argument #0 cannot be converted from 'SmallTime' to 'SmallTime' return formatter.format(self, fmt) ~~~~~~~~~~~~~~~~^~~~~~~~~~~ Included from /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/__init__.mojo:1: Included from /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/small_time.mojo:7: /home/mojo_user/ash_dynamics/lightbug_http/lightbug_http/external/small_time/formatter.mojo:83:8: note: function declared here fn format(self, m: SmallTime, fmt: String) -> String: 

Expected behavior
I propose eliminating the circular imports with a combination of Traits and __extension
