Bump rayon from 1.0.1 to 1.0.3

[dependabot-preview]

Bumps rayon from 1.0.1 to 1.0.3.

Changelog

Sourced from rayon's changelog.

Release rayon 1.0.3

• ParallelExtend is now implemented for tuple pairs, enabling nested
  unzip() and partition_map() operations. For instance, (A, (B, C))
  items can be unzipped into (Vec<A>, (Vec<B>, Vec<C>)).
  • ParallelExtend<(A, B)> works like unzip().
  • ParallelExtend<Either<A, B>> works like partition_map().
• ParallelIterator now has a method map_init() which calls an init
  function for a value to pair with items, like map_with() but dynamically
  constructed. That value type has no constraints, not even Send or Sync.
  • The new for_each_init() is a variant of this for simple iteration.
  • The new try_for_each_init() is a variant for fallible iteration.

Release rayon 1.0.2 / rayon-core 1.4.1

• The ParallelBridge trait with method par_bridge() makes it possible to
  use any Sendable Iterator in parallel!
  • This trait has been added to rayon::prelude.
  • It automatically implements internal synchronization and queueing to
    spread the Items across the thread pool. Iteration order is not
    preserved by this adaptor.
  • "Native" Rayon iterators like par_iter() should still be preferred when
    possible for better efficiency.
• ParallelString now has additional methods for parity with std string
  iterators: par_char_indices(), par_bytes(), par_encode_utf16(),
  par_matches(), and par_match_indices().
• ParallelIterator now has fallible methods try_fold(), try_reduce(),
  and try_for_each, plus *_with() variants of each, for automatically
  short-circuiting iterators on None or Err values. These are inspired by
  Iterator::try_fold() and try_for_each() that were stabilized in Rust 1.27.
• Range<i128> and Range<u128> are now supported with Rust 1.26 and later.
• Small improvements have been made to the documentation.
• rayon-core now only depends on rand for testing.
• Rayon tests now work on stable Rust.
