[bug] BLAS.lbt_forward undefined in Julia 1.6

[adrienbanse]

Bug description

If I'm not wrong,BLAS.lbt_forward (as well as the whole lbt.jl file in @stdlib/LinearAlgebra) is not defined in Julia 1.6. You should maybe increase the compat version of Julia in Project.toml.

Minimum (non-)working example

On Julia 1.6 REPL: using IntervalLinearAlgebra raises

ERROR: InitError: UndefVarError: lbt_forward not defined
Stacktrace:
 [1] getproperty
   @ ./Base.jl:26 [inlined]
 [2] __init__()

   @ Base ./loading.jl:936

during initialization of module IntervalLinearAlgebra

Expected behavior

The package should work on Julia 1.6 following Project.toml.

• IntervalLinearAlgebra.jl version: 0.1.6
