UNC path backslashes doubled

[Mephisto64]

The sharing address must have its backslashes doubled. (L'adresse du partage doit obligatoirement avoir ses anti-slashs doublés.)

With Error

const Smb = require('samba-client');
const samba = new Smb({
            'contoso.corp.local',
            'usr12345',
            'P@ssw0rd',
            '\\\\computername\\share'
        });
samba.getFile('file.txt', '/folder/file.txt');

...
\computernameshare: Not enough '\' characters in service

Without error

const Smb = require('samba-client');
const samba = new Smb({
            'contoso.corp.local',
            'usr12345',
            'P@ssw0rd',
            '\\\\\\\\computername\\\\\\share'
        });
samba.getFile('file.txt', '/folder/file.txt');

Correction proposal

Change your line 20

- this.address = options.address;
+ this.address = wrap(options.address);
