Update/Remove Deprecated Exercises

[rabestro]

Description:

Several exercises currently available on the Scala track have been marked as deprecated in the problem-specifications and require attention.

The following exercises are deprecated:

• beer-song:

  • Note: This exercise has been deprecated.
  • Action: Your track should implement "bottle-song" instead.
  • Upstream Issue: exercism/problem-specifications#2066

• trinary:

  • Note: This exercise has been deprecated.
  • Action: Your track should implement "all-your-base" instead.
  • Upstream Issue: exercism/problem-specifications#279

• accumulate:

  • Note: This exercise has been deprecated.
  • Action: Your track should implement "list-ops" instead.
  • Upstream Issue: exercism/problem-specifications#129

• binary:

  • Note: This exercise has been deprecated.
  • Action: Your track should implement "all-your-base" instead.
  • Upstream Issue: exercism/problem-specifications#279

• hexadecimal:

  • Note: This exercise has been deprecated.
  • Action: Your track should implement "all-your-base" instead.
  • Upstream Issue: exercism/problem-specifications#279

• octal:

  • Note: This exercise has been deprecated.
  • Action: Your track should implement "all-your-base" instead.
  • Upstream Issue: exercism/problem-specifications#279

These exercises should either be removed or replaced with their suggested alternatives to keep the Scala track up-to-date with the latest problem-specifications.

binary. hexadecimal, octal, and trinary are already deprecated in the track config. all-your-base has also been implemented so you'd just need to deprecate accumulate and beer-song in the track config. Then you need to add bottle-song and list-ops.

However, maintainers can choose to not deprecate exercises. accumulate is generally an easier exercise than list-ops so it may or may not be helpful to keep both.
