Prevent overflows by increasing  ring buffer size
Prevent overflows by increasing  ring buffer size

Via trial and error, I could verify that all google-api-rs
crates actually build if the ring-buffer is about 3 times
larger than before.

As the code is generated, some types are massive, and there
is more complexity than in hand-written code.

Increasing the buffer size should have no disadvantage, neither
to performance, nor on memory requirements.
