PrfKeyTemplates

- com.google.crypto.tink.prf.PrfKeyTemplates

```
@Deprecated
public final class PrfKeyTemplates
extends java.lang.Object
```
Deprecated.
Use PredefinedPrfParameters instead.
Key templates for PRF-Keys.
We recommend to avoid this class in order to keep dependencies small.
- Using this class adds a dependency on protobuf. We hope that eventually it is possible to use Tink without a dependency on protobuf.
- Using this class adds a dependency on classes for all involved key types.
These dependencies all come from static class member variables, which are initialized when the class is loaded. This implies that static analysis and code minimization tools (such as proguard) cannot remove the usages either.
Instead, we recommend to use KeysetHandle.generateEntryFromParametersName or KeysetHandle.generateEntryFromParameters.
