Subject: [PATCH] Follow the IOExpander_Base pull API of M5Unified 0.2.21

M5Unified 0.2.21 replaced IOExpander_Base::setPullMode(pin, bool) and
enablePull(pin, bool) with setPullMode(pin, gpio_pull_t), so the library no
longer compiled against it.

Call the new form (setPullMode(pin, pull_up), which writes the same two
register bits as the old pair) and require M5Unified >= 0.2.21 in
library.properties / library.json so the dependency is resolved by the
Library Manager and PlatformIO.
