it seems to me that NumericIO.jl is a bit behind?

- It’s still using `~/.juliarc.jl`, as it’s been replaced by `~/.julia/config/startup.jl` in Julia 1.0 ([.juliarc.jl in Julia1.0](https://discourse.julialang.org/t/juliarc-jl-in-julia1-0/14354))
- [REPL setup](https://github.com/ma-laforge/NumericIO.jl/#improved-repl-output-julia-console) in the README doesn’t work with Julia 1.7.

```julia
julia> using NumericIO
julia> Base.display(r::Base.REPL.REPLDisplay, v::Union{Float32,Float64}) = print(formatted(Base.REPL.outstream(r.repl), :SI, ndigits=4), v)
ERROR: UndefVarError: REPL not defined
Stacktrace:
 [1] getproperty(x::Module, f::Symbol)
   @ Base ./Base.jl:35
 [2] top-level scope
   @ REPL[7]:1

```
