Support for Disk/Memory Units Other Than GiB for --memory and --disk flags

[ngshiheng]

Description

Currently, the --memory or --disk flags allow users to specify the amount of memory allocated to the VM in Gibibyte (GiB).

Are there plans for Colima to support other units for CPU/Disk/MEM allocation, specifically Mebibyte (MiB)?

Suggestion 1

colima start --memory 2GiB
colima start --memory 512MiB

This change would provide flexibility to the users and make it easier to manage memory resources.

Suggestion 2

Alternatively, Colima can also support float (instead of only int) values for memory allocation. This would allow users to specify the exact amount of memory they want to allocate while keeping the unit as GiB.

Here is an example of how this could look:

colima start --memory 0.5 --disk 0.5 # GiB

The second suggestion is preferred as it would be backward compatible and not introduce breaking changes.

I have found myself requiring the exact same thing.
Running the smallest vm simply for a twingate connector would be a use case.

The support for specifying memory in decimals has been implemented in #1206.
