Bumped Weasel version to fix concurrency issue during Marten startup related to NpgsqlTypeMapping

[oskardudycz]

Per @Hawxy at Discord conversation, NpgsqlTypeMapping is causing the issue when starting multiple Marten instances in parallel:

Object reference not set to an instance of an object.

Changed NpgsqlTypeMapping to use ImHashMap for thread-safe usage.

See the fix in Weasel: JasperFx/weasel#84

Besides that:

• Adjusted StorageFeatures to not use IDictionary but thread-safe collections
• Updated also other Criter stack dependencies
