v27.1 is NOT 1.41.1 MSRV because of ureq

[DanGould]

ureq = "1.0" allows ureq 1.6 to be installed. 1.6 depends on once_cell v1.16.0 which is not msrv 1.41.1. once_cell 1.9.0 is te latest version of at msrv 1.41.1. once_cell 1.10.0 breaks it.

Unfortunately, ureq does not adhere to any MSRV, and only specifies once_cell = "1"

it seems this crate only has 1 ureq call, here https://github.com/RCasatta/bitcoind/blob/2c1758a2d5d638a388906c97bc011802b12e498b/build.rs#L106

so maybe the whole dependency could be replaced with something that maintains an MSRV

This is causing problems downstream. Kixunil/payjoin#36

Any suggestion to adhere to MSRV on 27.x branch is welcome

[DanGould]

Even with cargo update -p once_cell --precise 1.9.0 and building ureq in isolation msrv appears to be 1.54 for ureq 1.9.0. Further investigation is required.

@DanGould have a look at #102 which is a compromise, it allows MSRV 1.41.1 if the auto-download feature is not used

[RCasatta]

#102 (comment) I think it's solved
