Remove uneccessary static methods

CHANGELOG.md

@@ -35,6 +35,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 - BREAKING CHANGE: `tx.send()` is now asynchronous: old: `send(): TransactionId` new: `send(): Promise<TransactionId>` and `tx.send()` now directly waits for the network response, as opposed to `tx.send().wait()`
 - `Circuit.witness` can now be called outside circuits, where it will just directly return the callback result
+- BREAKING CHANGE: Static methods of type `.fromString()`, `.fromNumber()` and `.fromBigInt()` on `Field`, `UInt64`, `UInt32` and `Int64` are not longer supported.
 
 ### Deprecated
