restler dependency is very outdated

[matthewmayer]

Client version

4.3.2

Expected behaviour

installing sendwithus installs a minimal number of packages.

Actual behaviour

npm i sendwithus depends on restler, which hasnt been updated for 6 years, and depends on a large number of packages, many of which report security issues.

up to date, audited 314 packages in 8s

33 vulnerabilities (11 low, 13 moderate, 8 high, 1 critical)

To address all issues, run:
  npm audit fix

Suggest to switch from restler to something like node-fetch

Steps to reproduce

npm i sendwithus
