Refactor subcommands into (stackable) options

Additions

• Subcommands that used to be mutually exclusive can now be stacked because they have become CLI options. Example: semver -st sorts versions and then prints them in a custom (TSV) format.

Changes

• Former subcommand functionality has been condensed into the main semver command, and is activated by CLI options (#45).

Removals

• semver grep -c (pipe semver output to wc instead).
• semver find (pipe find output to semver instead).
• semver sort -r (pipe semver -s output to tac instead).

Bring the subcommands in line with POSIX conventions

Additions

• Add semver find.
• Add semver printf.
• Support the -c (count) option in semver grep.
• Support the -o (only-matching) option in semver grep.
• Support the -q (quiet) option in semver grep.

Changes

• Provide substitute wrapper functions for version increment operations in the README.

Removals

• Remove semver compare (most shell use cases are covered by semver sort).
• Remove semver decrement-*.
• Remove semver increment-*.
• Remove semver init.
