reporting error in AssemblyScript build

[jlwaugh]

via km1tz on Discord:

"Error is thrown in build time inside near-sdk-core package."

Error Message

ERROR TS2304: Cannot find name 'encode'.
       this.setBytes(key, encode<T>(value));
 in ~lib/near-sdk-core/storage.ts(158,26)

ERROR TS2304: Cannot find name 'decode'.
     return decode<T>(bytes);
 in ~lib/near-sdk-core/util.ts(46,12)

"While inspecting further, I can see that encode and decode functions are defined inside near-sdk-core\assembly\as_types.d.ts and cannot figure out where is the problem. I've tried updating near-sdk-core and typescript compiler to latest version to latest version but it did not make any difference."
