Nightly Release

This is a rolling release built from the latest develop branch.

samedec-0.4.0: The Spring 2024 Update

Are you "Weather Ready?" This release is mostly compatible with
previous versions but adds more SAME codes and environment
variables.

ENHANCEMENTS

* Support the following new SAME codes:

  * EAN: Renamed to National Emergency Message
  * NAT: National Audible Test
  * NST: National Silent Test
  * FSW: Flash Freeze Warning
  * FZW: Freeze Warning
  * HLS: Hurricane Local Statement
  * SQW: Snow Squall Warning

* Discontinue the `SAMEDEC_SIGNIFICANCE` level of "`M`"
  (Message), which is not found anywhere in the standards
  document. The following messages are upgraded to
  Statement:

  * ADR: Administrative Message
  * NMN: Network Message Notification

* Improved detection of National Weather Service vs
  Environment Canada. samedec will no longer output a
  generic `SAMEDEC_ORIGINATOR` of "`Weather Service`."
  Instead, samedec will output either
  "`National Weather Service`" or "`Environment Canada`."

* New environment variables for child processes

  * `SAMEDEC_IS_NATIONAL`: "`Y`" for national activations;
    otherwise present but empty

  * `SAMEDEC_SIG_NUM`: a numeric representation of the
    significance level

* Add proper integration test scripts for child processes

FIXES

* IMPORTANT: Fix code entry for ADR (Administrative Message),
  which was previously wrong.

* Handle EOF within the main app. Child processes are now
  spawned even for very short input files.

* Update to Edition 2021

* Replace is-terminal with terminal_size

samedec-0.3.0: Add fallback decoding

ENHANCEMENTS

* CLI-BREAKING: Suppress duplicate messages which follow
  each other quickly in time. This mainly affects Fast EOMs:
  now only one "`NNNN`" line will be printed per SAME
  message. Some users may consider this breaking.

* CLI: Add fallback decoding which can decode SAME headers using
  only two bursts. The improved decoder adds a delay of
  **1.311 seconds** when reporting a Start Of Message. Since the
  SAME voice message is often prefixed with an extended period of
  silence and/or a Warning Alarm Tone, the additional delay
  should not impact most applications.

FIXES

* Fix decoding of back-to-back SAME messages when either or both
  have missed bursts

* Update dependencies

samedec-0.2.5: CLI Improvements

ENHANCEMENTS

* Update to chrono 0.4.23 and replace
  deprecated functions.

* Update to clap v4. Improve help text and
  general CLI behaviors.

FIXES

* samedec now errors on startup if reading
  from stdin and stdin is a terminal

samedec-0.2.4: Maintenance release

CI binaries are now available on the Github
Releases tab. These binaries are built with
Github Actions on Github Workers.

ENHANCEMENTS

* Log the full text of each SAME burst

FIXES

* RUSTSEC-2022-0078: bump bumpalo to 3.12.0

* RUSTSEC-2021-0047: replace slice-deque with
  slice-ring-buffer

* Documentation improvements
