Update hecs requirement from 0.7.6 to 0.9.1

[dependabot]

Updates the requirements on hecs to permit the latest version.

Changelog

Sourced from hecs's changelog.

0.9

Changed

• Updated World::get_unchecked to match 0.8's changes to World::get

0.8.3

Added

• CommandBuffer::{insert_one, remove_one} convenience methods (thanks tesselode!)

0.8.2

Removed

• APIs deprecated in 0.7

0.8.1

Fixed

• Empty archetypes no longer participate in dynamic query borrow-checking

0.8.0

Added

• World::satisfies and EntityRef::satisfies to check if an entity would match a query

Changed

• Many generic methods that previously took a Component now instead take either a ComponentRef<'a> or a Query to improve consistency with queries and address a common footgun:
  • World::get, EntityRef::get, and Archetype::get now take shared or unique references to component types.
  • Since World::get_mut and EntityRef::get_mut have been subsumed by their respective get methods, they have been removed.
  • EntityBuilder and EntityBuilderClone's get and get_mut were refactored along the same lines for consistency. However, the get_mut method was not removed for these types since they do not perform dynamic borrow checking.
  • The With/Without query transformers now take a query that entities must/mustn't match rather than a component type. Additionally, the order of their generic arguments was reversed to place the query whose results will be yielded first.
• SerializeContext traits now take their serializer arguments by value, and must call end() themselves.

0.7.7

Added

• Entity::DANGLING convenience constant

Fixed

• Various bad behavior when dangling Entity handles are used
• Inconsistent component counts in column serialization
