v0.3.0

• Fix regression: Forbid bare schema in which a type is repeated in an union

  The following schema is now correctly reported as invalid:

  type X (u8 | u8)
  

• Deduplicate readers and writers of complex non-aliased types

  @bare-ts/tools generates readers and writers for complex non-aliased types.
  These reader and writer are now de-duplicated.

• Default to null instead of undefined for optional types

  The use of null seems more common than the use of undefined.

  The option --use-null is removed.
  A new option --use-undefined is added.

• Make configurable the emitted type for void type

  BARE schema enable use of void types in unions. For example:

  type Union (u8 | void)
  

  Previously, @bare-ts/tools emitted the type undefined for void.
  Now it relies on options --use-undefined and --use-lax-optional to
  choose between null, undefined, and null | undefined.
  Note that these options also modify the emitted types for optionals.

• Support for quoted properties

  The option --use-quoted-property enables to output
  quoted properties instead of unquoted properties.

  This can be useful when using a JS minifier that differently handles
  quoted and unquoted properties.
