GC-related segfault on Windows with readtable()

[niclasmattsson]

I consistently get a segfault when trying to call readtable() as below. The file used can be downloaded here. It's the second url in the Download section, the one called "2019 National Emissions v1.0 (metadata)". I'm on Julia 1.5.1 using Windows 10, running XLSX v0.7.3.

julia> XLSX.readtable("National_Carbon_Emissions_2019v1.0.xlsx", "Territorial Emissions", "A17:HW77")
GC error (probable corruption) :
Allocations: 61016032 (Pool: 60995506; Big: 20526); GC: 59
