OT-2 should support TLS > 1.0 for 802.1x connections

[mcous]

Overview

The OT-2 is currently only capable of connecting to 802.1x Wi-Fi networks that use TLS 1.0. This is a very old version of TLS, and its use is being (and has been) phased out.

Currently, the OT-2 appears to be using LibreSSL 2.7.4. The latest version of LibreSSL is 3.5.2.

Acceptance Criteria

• [ ] An OT-2 can connect to a 802.1x network using TLS 1.1, 1.2, or 1.3

Implementation Notes

We should investigate whether #148 has any affect on this issue. As noted in that PR, we'll be switching to OpenSSL rather than LibreSSL.
