Method readMemoryChunks

* Make one or more memory reads and update values. For the caller, it should look like a single * memory read but, if one read fails, all reads are considered as failed. * * @param startAddr The start address of the memory region. Everything else is relative to `startAddr` * @pa

(
        session: vscode.DebugSession, startAddr: number, specs: AddrRange[], storeTo: number[])

     * @param storeTo This is where read-results go. The first element represents item at `startAddr`
