esp-println fails to build with anything but auto feature

[theembeddedrustacean]

The build fails when attempting to activate the jtag-serial or uart features for the esp-println crate. For example, when doing the following:

esp-println = { version = "0.13.0", features = ["esp32c6", "log", "jtag-serial"] }

The build fails with the following error:

ERROR: expected exactly one enabled feature from feature group:
  ["jtag-serial", "uart", "auto"]

error: proc macro panicked
  --> /Users/omarhiari/.cargo/registry/src/index.crates.io-6f17d22bba15001f/esp-println-0.13.0/build.rs:12:5

   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

   = help: message: Build failed
   = note: this error originates in the macro `assert_unique_used_features` (in Nightly builds, run with -Z macro-backtrace for more info)

error: could not compile `esp-println` (build script) due to 1 previous error

This does not make much sense since exactly one of the listed features is being enabled.

You need to opt-out of the default features (

esp-hal/esp-println/Cargo.toml

Line 29 in 2ff28b1

default = ["critical-section", "colors", "auto"]

) via default-features=false (and add the wanted features since none of them will be enabled then)
