Version 0.4.0

Added

• ✨ A -m (max) flag, which limits the number of times the supplied command is executed. (#82; thanks @tumdum!)
• A rudimentary set of smoke-tests.

Changed

• Updated our clap dependency from 2.33.0 to 2.33.2
• Updated our (optional) simple_logger dependency from 1.6.0 to 1.12.1.
• Updated our log dependency from 0.4.8 to 0.4.11
• Updated our rand dependency from 0.7.3 to 0.8.4

Removed

• Breaking: Removed the eb::clamp function, which is replaced by the now-stabilized core::cmp::Ord::clamp function.

  The core::cmp::Ord::clamp function was added in Rust 1.50.0, which was released on 2021-02-11. If you haven't upgraded yet, you'll need to in order to compile the new version of eb.
