Breaking Change v3.8.0 => v3.9.0

System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow.js): No
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows
• TensorFlow.js installed from (npm or script link): npm
• TensorFlow.js version (use command below): 3.9.0

Describe the current behavior

Upgraded from 3.8.0 to 3.9.0, and typescript throws an error:

Error: node_modules/@tensorflow/tfjs-core/dist/hash_util.d.ts:2:49 - error TS2304: Cannot find name ‘Long’.

Using typescript 4.3.5.

Perhaps missing import Long from 'long'; in

Describe the expected behavior

No breaking change

I am also having the same issue on a fresh Angular 12 install… Version is 3.11.0

When I manually add /// <reference types="long" /> to the hash_util.d.ts it works as expected.

Before

/// <amd-module name="@tensorflow/tfjs-core/dist/hash_util" />
export declare function hexToLong(hex: string): Long;
export declare function fingerPrint64(s: Uint8Array, len?: number): Long;

After

/// <amd-module name="@tensorflow/tfjs-core/dist/hash_util" />
/// <reference types="long" />
export declare function hexToLong(hex: string): Long;
export declare function fingerPrint64(s: Uint8Array, len?: number): Long;

v3.12.0

Added @types/long to my compilerOptions.types worked.
