Subject: [PATCH] chore: change `tracing-subscriber` dependencies to enable
 `std`

## Motivation

Currently, some `tracing-subscriber` dependencies in other crates use
`default-features = false`, to ensure that unneeded default features of
`tracing-subscriber` are not inadvertently enabled. However, some of the
features those crates enable also require the `std` feature flag. The
`default-features = false` config _disables_ the `std` feature, so the
required features are not available.

## Solution

This branch changes those crates' dependencies on `tracing-subscriber`
to also enable the `std` feature.

## Alternatives

As an alternative solution, we could change `tracing-subscriber`'s
feature flags so that features that require the standard library _also_
enable the `std` feature, rather than having those features _require_
it. I think this _might_ actually provide a better experience for most
users.
