BrowserFS.configure never report error for IsoFS in BrowserFS v1.x

[1koval]

https://github.com/jvilk/BrowserFS/blob/8ed7c19ab12896b7479527f5570975f2ca3349bf/src/backend/IsoFS.ts#L1176

    } catch (e) {
      e = e;
    }

e = e typo leads to lost error code (error never reported to a caller).

To reproduce:

var BrowserFS = require("browserfs");
var Buffer = BrowserFS.BFSRequire('buffer').Buffer;

// Workaround for https://github.com/jvilk/BrowserFS/issues/250
var size = 18 * 2048;
var broken_iso = Array(size);
for (var i=0;i<size;i++) {
    broken_iso[i]= 255; // VolumeDescriptorSetTerminator
}

var mountConfig = {
    fs: "MountableFileSystem",
    options: {
        "/iso": {
            fs: "IsoFS",
            options: {
                data: Buffer.from(broken_iso),
                name: 'name'
            }
        }
    }
};
BrowserFS.configure(mountConfig, function (e) {
    if (e) {
        console.log('never');
   }
   console.log('always');
});
console.log('always');

Potential fix:

    } catch (ex) {
      e = ex;
    }

More advanced fixes already in 2.x branch.

If would be nice to resolve it in production 1.x release.
