Loosen dependency pins: cachetools, aiohttp, requests

[socketz]

Summary

Loosens overly strict dependency pins that cause conflicts with other packages in the same environment.

Fixes #127

Changes

Dependency	Before	After	Reason
cachetools	==4.2.0	>=4.2,<8	Hard pin to a 6-year-old version blocks users with other packages requiring cachetools>=5/6/7. Tested compatible with cachetools 7.0.5.
aiohttp	>=3.12.14,<=4	>=3,<4	<=4 only allowed exactly 4.0.0, unintentionally excluding 4.0.1+. Changed to <4 to correctly express the intent of staying on the v3 series.
requests	>=2.18.4	>=2.18.4,<3	Added upper bound to avoid unexpected breakage if a future v3 introduces breaking changes.

Testing

All existing tests pass with cachetools 7.0.5 and the updated constraints.

Pull request overview

This PR loosens dependency constraints in the Python package metadata to reduce install-time conflicts for consumers (Fixes #127).

Changes:

• Relax cachetools from a hard pin (==4.2.0) to a range (>=4.2,<8).
• Correct aiohttp’s upper bound semantics by switching from <=4 (effectively <=4.0.0) to <4.
• Add an upper bound for requests (<3) to avoid potential future breaking changes.

Sorry for the AI-assisted approach — but this is a well-known pain point that's been affecting users for a while, and since the fix is straightforward, it felt worth resolving quickly rather than waiting.

Thanks @socketz. No worries for the AI usage, we're ok with it if done well, also we're in this situation because of another AI PR. :)

By the way I ran tests locally since we need the IPINFO_TOKEN to properly run them and it's not available in CI for PRs from forks. I had to make a small fix but they work. 👍

Merging and drafting a release.
