Compatibility with ESP32

[Grimaction]

Hi, is this library compatible with ESP32?

I've got an error on encode example:

Base64Encode:32:23: error: 'Base64' was not declared in this scope; did you mean 'base64'?
32 | int encodedLength = Base64.encodedLength(inputStringLength);
| ^~~~~~
| base64
exit status 1
'Base64' was not declared in this scope; did you mean 'base64'?
