Unable to manage overrun for USART

[Maldus512]

I'm trying to use the USART2 peripheral on my stm32f030RC. I'm not using interrupts, so from time to time an overrun interrupt is to be expected (and is acceptable); however I am unable to manage the error with the tools provided by the API.
When an overrun occurs the serial.read method returns an error accordingly, but:

• the Peripheral.USART2 reference has been passed to the Serial object, so I cannot access its ICF register to clear the ORE bit.
• I cannot set the OVRDIS bit and ignore every overrun because the Serial constructor resets the CR3 register (https://docs.rs/stm32f0xx-hal/0.14.1/src/stm32f0xx_hal/serial.rs.html#350); I cannot change it afterwards because the USART2 reference is gone and that bit cannot be changed while the peripheral is on.

How do I manage overrun errors? Either clearing the flag or disabling it altogether would be fine for me.

Edit: this problem would be resolved by PR #63
