Fix issues in network adapter and core getStatus(), getStatuses()

[Xelio]

• core getStatus(): change buffer.write() to adapter.write(), buffer.write() does not send data to print immediately.
• core getStatuses(): change to retrieve status one by one, because network printer does not return all 4 status in the same read() operation.
• core: add error handling in getStatus() and getStatuses().
• network adapter open(): remove err from connectListener of .connect(), it does not have err param.
• network adapter read(): change .on() to .once(), callback should only run once for current read operation.
• network adapter: add read timeout. When read timeout, pass empty buffer to callback function.
• network adapter: add test of getStatus(), getStatuses().
• export StatusJSON, StatusJSONElement, StatusJSONElementSingle, StatusJSONElementMultiple

Hi @dohooo, This PR is mainly for network printer. I only has network printer, so can't test it on USB/Serial/BT printer. Would you help to test on USB/Serial/BT printer, and see if there is any problem?

@Xelio Thanks for your effort, awesome work! But before I merge it, could you add a changeset for these changes? BTW, Can you add unit test for this PR.

[KylianJay]

Looking forward to this release! Will probably fix many of the issues I am having, as I use Network printer for my main use-case. No rush, but add a changeset and unit test please?
