message: Update BREAKING.md for instructions on using PrimedComponentFactory
diff: Previously, the root provided by `PrimedComponent` was a `SharedMap`. Now it is a `SharedDirectory`.
  -This should be compatible for usage (e.g. existing calls to `get`, `set`, `wait`, etc. should work as before), but explicit type checks against `SharedMap` or `ISharedMap` should be updated to `SharedDirectory` and `ISharedDirectory` respectively.
  +This should be compatible for usage (e.g. existing calls to `get`, `set`, `wait`, etc. should work as before), but explicit type checks against `SharedMap` or `ISharedMap` should be updated to `SharedDirectory` and `ISharedDirectory` respectively. Additionally, if your component is currently using a `SharedComponentFactory` you'll want to instead use a `PrimedComponentFactory` which will register the correct root factories on your behalf.

  +Before:
  +```typescript
  +export const ClickerInstantiationFactory = new SharedComponentFactory(
  + Clicker,
  + [
  + SharedMap.getFactory([new CounterValueType()]),
  + ],
  +);
  +```
  +
  +After:
  +```typescript
  +export const ClickerInstantiationFactory = new PrimedComponentFactory(
  + Clicker,
  + [],
  +);
  +```
  +
  +Alternatively you can register the `SharedDirectory` factory yourself (similar to how you were already registering the `SharedMap` factory), but the `PrimedComponentFactory` is recommended.
  ## Handles to SharedObjects must be used on map sets
