yargs-parser v17.0.0

⚠ BREAKING CHANGES

• this reverts parsing behavior of booleans to that of yargs@14
• objects used during parsing are now created with a null
  prototype. There may be some scenarios where this change in behavior
  leaks externally.

Features

• boolean arguments will not be collected into an implicit array (#236) (34c4e19)
• introduce nargs-eats-options config option (#246) (d50822a)

Bug Fixes

• address bugs with "uknown-options-as-args" (bc023e3)
• array should take precedence over nargs, but enforce nargs (#243) (4cbc188)
• support keys that collide with object prototypes (#234) (1587b6d)
• unknown options terminated with digits now handled by unknown-options-as-args (#238) (d36cdfa)
