pop_runica EEG structure mis-named

[zenBen]

Description

The EEG data structure is given the wrong name 'data' on line 357 of pop_runica
Variable 'data' is not defined and the function thus throws an error, as below.

`Undefined variable "data" or class "data.chanlocs.type".

Error in pop_runica (line 357)
datatype = {data.chanlocs.type};`

#### Steps to Reproduce

1. Run ICA from a script using FastICA option

#### Expected behavior: pop_runica will compute ICA and create ICA matrices in the EEG structure
#### Actual behavior: pop_runica throws 'undefined vairable "data"' error.
#### Versions

OS version	Debian Linux
Matlab version	r2019a
EEGLAB version	development / latest from github
