Add helpers for base64url encoding. base64url is a variant of base64 that uses a URL-safe alphabet. It can be constructed from base64 by replacing the '+' and '/' characters with '-' and '_' respectively. Many implementations also strip the padding, although this is not required by the spec [1]. This will be used in upcoming patches for Azure Key Vault requests that require base64url-encoded payloads.
