Edward Betts ea4980a5d7 Fix European trip return heuristic for weekend location tracking

Adjust European short trip heuristic from >3 days to >1 day to correctly
detect when user has returned home from European trips. This fixes the
April 29-30, 2023 case where the location incorrectly showed "Sankt Georg, Hamburg"
instead of "Bristol" when the user was free (no events scheduled) after
the foss-north trip ended on April 27.

The previous logic required more than 3 days to pass before assuming
return home from European countries, but for short European trips by
rail/ferry, users typically return within 1-2 days.

merge-stream

Merge (interleave) a bunch of streams.

Synopsis

var stream1 = new Stream();
var stream2 = new Stream();

var merged = mergeStream(stream1, stream2);

var stream3 = new Stream();
merged.add(stream3);
merged.isEmpty();
//=> false

Description

This is adapted from event-stream separated into a new module, using Streams3.

API

`mergeStream`

Type: function

Merges an arbitrary number of streams. Returns a merged stream.

`merged.add`

A method to dynamically add more sources to the stream. The argument supplied to add can be either a source or an array of sources.

`merged.isEmpty`

A method that tells you if the merged stream is empty.

When a stream is "empty" (aka. no sources were added), it could not be returned to a gulp task.

So, we could do something like this:

stream = require('merge-stream')();
// Something like a loop to add some streams to the merge stream
// stream.add(streamA);
// stream.add(streamB);
return stream.isEmpty() ? null : stream;

Gulp example

An example use case for merge-stream is to combine parts of a task in a project's gulpfile.js like this:

const gulp =          require('gulp');
const htmlValidator = require('gulp-w3c-html-validator');
const jsHint =        require('gulp-jshint');
const mergeStream =   require('merge-stream');

function lint() {
  return mergeStream(
    gulp.src('src/*.html')
      .pipe(htmlValidator())
      .pipe(htmlValidator.reporter()),
    gulp.src('src/*.js')
      .pipe(jsHint())
      .pipe(jsHint.reporter())
  );
}
gulp.task('lint', lint);
