`$imports` is now a separate named export rather than a property of the
default export.

After converting the module under test to an ES module the mocked functions are now properties of the default export rather than named exports.

Use the convert-to-es-modules script from the frontend-toolkit repo to
convert src/sidebar/store to ES modules.

Convert src/sidebar/services to ES modules

This comment was copied from the line where the `CACHE_TTL` var was
defined when converting to ES modules.

This imports from `src/sidebar/services` so it needed to be converted at
the same time as the modules in that directory.

Move an `events` export from being a property of the default export to a
separate named export, which is more appropriate for ES modules.

Use the convert-to-es-modules script from the frontend-toolkit repo to
convert services to ES modules.

Move new-annotation initialization into the store

Bump core-js from 3.4.8 to 3.6.3

Bump @sentry/browser from 5.10.2 to 5.11.0

Move initialization for new (unsaved) annotations from the (legacy)
annotation component’s controller into the `annotations` store module.

Bump preact from 10.1.1 to 10.2.1

Bump sass from 1.24.2 to 1.24.4

Convert src/sidebar/components to ES modules

This mocking broke after the ES module conversion. Since the mocked
module just exports a set of constants, we can just avoid mocking it.

Export `updateModel` as a separate export rather than a property of the
default export, since this is how the test expects to import it.

Use the convert-to-es-modules package from the frontend-toolkit repo to
convert CommonJS/Node require syntax to ES modules.

As well as the module syntax conversion, this script also has the effect
of normalizing the sorting and grouping of imports according to the
following convention:

 - Imports are grouped into 3 categories: Vendor, same package but other
   directory (as calling module), same directory as calling module
 - Imports are sorted by module path

Import specifiers are untouched.

Convert sidebar entry point to ES modules

Bump sinon from 8.0.2 to 8.0.4

Use the `convert-to-es-modules` script from the
hypothesis/frontend-toolkit repo to convert the sidebar entrypoint to ES
modules.

Because the code generated for `import` includes interop code to support
either ES or CommonJS modules, but migrating a module with a default
export changes its exports object, we need to migrate the module graph
"top-down" (ie. convert a module, then its dependencies).

Hoist CommonJS imports to top of file

In preparation for conversion to ES modules, hoist some remaining
non-top level `require` calls to the top level of the file.

Normalize module imports to an ES module-friendly format

In preparation for conversion to ES imports, hoist Node/CommonJS imports
to the top level of the module.
