cargo install rustic-rs failed (E0308)

[9-2-1]

I have used to build rustic-rs in termux (an android terminal emulator), and failed to build v0.8.1 while v0.8.0 and v0.7.0 were OK.

error: could not compile `rustic-rs` (lib) due to 1 previous error

Likely because rustic-rs depends on rustic_core==0.3.1
while rustic-rs depends on rustic-backend, which depends on the latest rustic-core (==0.4.0 now)
which are different.

Did you try installing with cargo install --locked rustic-rs to utilize the generated lockfile?

EDIT: I checked with --locked and pushed a fix to the readme and online docs, so this is more obvious as a workaround in these cases.

It works, thank you!
