`EPERM: File not opened with a readable mode` error

[Davilarek]

Hello,

window.ZenFS.configure({
            backend: window.ZenFS_DOM.IndexedDB,
            storeName: "VirtualFS",
            idbFactory: indexedDB,
        }).then(() => {
            window.ZenFS.fs.writeFileSync("/test.txt", "hello world!");
        });

This code produces errors on dom 0.2.1 and core 0.7.8

Uncaught (in promise) Error: EPERM: File not opened with a readable mode.
    f ApiError.ts:139
    readSync file.ts:599

    run test.js:14

It seems that this.flag contains w flag in the read function.

@Davilarek,

Thank you for submitting this issue! Just observing the stack trace, this is an issue with core not anything from dom, so I've transferred the issue.

Changing the default flag in the normalizeOptions call should fix this issue.

Does v0.7.11 fix your issue?

Looks like so, thanks
