Feature request: read_excel to support hyperlinks split into label and hyperlink
Situation:
.xlsx file having a column with label and hyperlinks (see screenshot collage)
In Excel, label: Python (that has a hyperlink to i.e.: www.python.org)
#### Code Sample, a copy-pastable example if possible

data = pd.read_excel('Book1.xlsx')
column has just "Python" as content. Hyperlink information is lost.
(see screenshot)

#### Expected Output, Proposal:

Add an argument  for example named hyperlinkparser to read_excel()
that offers options: "label", "hyperlink", "both"
label ... just the label (this is how it is handled now)
hyperlink ... just the hyperlink, drop the label
split ... created two separate columns for label and hyperlink each

with example it could look like:
         | MyLinks | MyLinks_hyperlink
0       | Python   | www.python.org

btw. openpyxl 2.4.+ has this feature now included (was broken in previous versions). Maybe this helps for implementation.

Thank you!
