Warnings from node-gyp

[dilyanpalauzov]

Using node-zopfi-es prints these warnings:

warning node-zopfli-es > node-gyp > mkdirp@0.5.4: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
warning node-zopfli-es > node-gyp > request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
warning node-zopfli-es > node-gyp > tar > mkdirp@0.5.4: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

BLOCKED: node-gyp needs to update their dependencies.

nodejs/node-gyp#2084

the request error is blocked by my own pull request on node-coveralls that i have to finish:
nickmerwin/node-coveralls#275

this should be fixed in version 1.0.5 onwards.
