issue regarding Install dependency for HCodecs version

[kaijCH]

While installing Euterpea from cabal using command "cabal v1-install Euterpea", I found HCodecs-0.5.1 was required and always failed while building So I check on Hackage.Haskell.org, figured out there exist HCodecs-0.5.2; As assuming the fail of build is due to out-of-date version, I separately install HCodecs-0.5.2, (which run succeed), then tried run "cabal v1-install Euterpea" again, to my surprise, the install did not skip version check for HCodes even I installed a latest version of HCodecs-0.5.2

Here is the log the reflecting my separate install of HCodecs-0.5.2 & the fail building of installing HCodecs0.5.1:

HCodecs-0.5.1-KovArVTnpFnLaEvHYYD8GP failed during the building phase. The exception was: ExitFailure 1

that is mist confusing, for the version check did not skip Hcodecs-0.5.1

Merging #38 will fix this.

Okay I just want to share the solution here after having another hints from StackOvewrflow: using an extra param in cabal install:

cabal v1-install --allow-newer Enterpea link: https://stackoverflow.com/questions/64841853/issue-while-haskell-instaling-euterpeas-dependency-hcodecs-did-not-skip-versio/64842069#comment114649123_64842069

should have solved the dependencies check; I could finish the function check for Euterpea by now, hoping this add up could help anyone who may strugle with install from cabal and dont want to "get hand dirty" by further configure cabal's self configure file..

Although I hope Euterpea could have this solution label in instruction before they modified their Euterpea.cabal, so until then I think it might be better to keep this issue open and let someone later struggling see this
