Bumps jszip from 3.1.5 to 3.7.1.

Changelog

Sourced from jszip's changelog.

v3.7.1 2021-08-05

• Fix build of dist files.
  • Note: this version ensures the changes from 3.7.0 are actually included in the dist files. Thanks to Evan W for reporting.

v3.7.0 2021-07-23

• Fix: Use a null prototype object for this.files (see #766)
  • This change might break existing code if it uses prototype methods on the .files property of a zip object, for example zip.files.toString(). This approach is taken to prevent files in the zip overriding object methods that would exist on a normal object.

v3.6.0 2021-02-09

• Fix: redirect main to dist on browsers (see #742)
• Fix duplicate require DataLengthProbe, utils (see #734)
• Fix small error in read_zip.md (see #703)

v3.5.0 2020-05-31

• Fix 'End of data reached' error when file extra field is invalid (see #544).
• Typescript definitions: Add null to return types of functions that may return null (see #669).
• Typescript definitions: Correct nodeStream's type (see #682)
• Typescript definitions: Add string output type (see #666)

v3.4.0 2020-04-19

• Add Typescript type definitions (see #601).

v3.3.0 2020-04-1

• Change browser module resolution to support Angular packager (see #614).

v3.2.2 2019-07-04

• No public changes, but a number of testing dependencies have been updated.
• Tested browsers are now: Internet Explorer 11, Chrome (most recent) and Firefox (most recent). Other browsers (specifically Safari) are still supported however testing them on Saucelabs is broken and so they were removed from the test matrix.

v3.2.1 2019-03-22

• Corrected built dist files

v3.2.0 2019-02-21

• Update dependencies to reduce bundle size (see #532).
• Fix deprecated Buffer constructor usage and add safeguards (see #506).
