Compatibilitty problems with mat_to_mpo function

[jmsett]

Using:

---

using ITensors
using ITensorMPS
using ITensorQTT

---

and locally installed Julia packages:

---

IJulia v1.25.0
ITensorMPS v0.2.4
ITensorQTT v0.0.1 https://github.com/ITensor/ITensorQTT.jl.git#main
ITensorTDVP v0.4.7
ITensors v0.6.16

Some functions are not exported correctly from main/src/function_to_mps.jl. While function_to_mps, mps_to_discrete_function, and mpo_to_mat are working well, I get the following error for mat_to_mpo:

---

UndefVarError: mat_to_mpo not defined
