[dependabot]

Bumps async to 2.6.4 and updates ancestor dependency firebase-tools. These dependencies need to be updated together.

Updates async from 3.2.0 to 2.6.4

Changelog

Sourced from async's changelog.

v2.6.4

• Fix potential prototype pollution exploit (#1828)

v2.6.3

• Updated lodash to squelch a security warning (#1675)

v2.6.2

• Updated lodash to squelch a security warning (#1620)

v2.6.1

• Updated lodash to prevent npm audit warnings. (#1532, #1533)
• Made async-es more optimized for webpack users (#1517)
• Fixed a stack overflow with large collections and a synchronous iterator (#1514)
• Various small fixes/chores (#1505, #1511, #1527, #1530)

v2.6.0

• Added missing aliases for many methods. Previously, you could not (e.g.) require('async/find') or use async.anyLimit. (#1483)
• Improved queue performance. (#1448, #1454)
• Add missing sourcemap (#1452, #1453)
• Various doc updates (#1448, #1471, #1483)

v2.5.0

• Added concatLimit, the Limit equivalent of concat (#1426, #1430)
• concat improvements: it now preserves order, handles falsy values and the iteratee callback takes a variable number of arguments (#1437, #1436)
• Fixed an issue in queue where there was a size discrepancy between workersList().length and running() (#1428, #1429)
• Various doc fixes (#1422, #1424)

v2.4.1

• Fixed a bug preventing functions wrapped with timeout() from being re-used. (#1418, #1419)

v2.4.0

• Added tryEach, for running async functions in parallel, where you only expect one to succeed. (#1365, #687)
• Improved performance, most notably in parallel and waterfall (#1395)
• Added queue.remove(), for removing items in a queue (#1397, #1391)
• Fixed using eval, preventing Async from running in pages with Content Security Policy (#1404, #1403)
• Fixed errors thrown in an asyncifyed function's callback being caught by the underlying Promise (#1408)
• Fixed timing of queue.empty() (#1367)
• Various doc fixes (#1314, #1394, #1412)

v2.3.0

• Added support for ES2017 async functions. Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an async function. Previously, you had to wrap async functions with asyncify. The caveat is that it will only work if async functions are supported natively in your environment, transpiled implementations can't be detected. (#1386, #1390)
• Small doc fix (#1392)

v2.2.0

• Added groupBy, and the Series/Limit equivalents, analogous to _.groupBy (#1364)
• Fixed transform bug when callback was not passed (#1381)
• Added note about reflect to parallel docs (#1385)

v2.1.5

• Fix auto bug when function names collided with Array.prototype (#1358)
