fix(util): addFromURL with URL-escaped file names

chore: use tildes for pre-v1 deps

Investigation discovered that pong responses CAN have `time: 0` (they can be very quick). Previously pong messages were differentiated by time greater than 0, but considering it can be 0 this was incorrect.

fix: correctly differentiate pong responses

Big.js just released an update that added esmodule support by adding a "module" field to their package.json. By default, webpack will use this field when requiring a module. Since esmodules aren't fully supported in the browser and we don't do any transpiling this PR configures webpack to not consider the esmodule field.

[Webpack `mainFields` docs](https://webpack.js.org/configuration/resolve/#resolve-mainfields)

[Why `require('big.js')` is broken for us](webpack/webpack#4742)

Refs ipfs/js-ipfs#1363

Note that this solves the issue for `big.js`, but also for any other modules in the future that decide to define a `module` field in their `package.json` or any that already do and we just haven't realised it yet!
