compileFile() has a different return then compile()

[BananaAcid]

compile() returns fn(locals, callback) -- expected, is like pug
https://github.com/pugjs/then-pug/blob/master/packages/then-pug/lib/index.js#L384

compileFile() returns type stream -- unexpected, should be like compile()
https://github.com/pugjs/then-pug/blob/master/packages/then-pug/lib/index.js#L477

Workaround :

import {promises as fs} from 'fs';

async function renderAsync(filepath, locals) {
  
  let options = {filename: filepath};
  let fn = pug.compile(await fs.readFile(options.filename, 'utf8'), options);
  
  // promise helper
  return new Promise( ret => fn(locals, (e,r) => ret(r)) );
}

let html = await renderAsync('filename', {...locals});

Thanks for the report.

I must admit that I never used compileFile in then-pug because it reads file synchronously so I am not surprised its behavior is not as expected.

I will have to think whether it should be removed altogether from then-pug or see how we can patch the caching mechanism in handleTemplateCache

The only reason for me, was because of a different caching method I implemented (using LRU).
